The open-source database your agents read, write, and react to

DatabaseDeveloperAnalyticsAutomationStorage

PostgreSQL is the world's most advanced open-source relational database — trusted for ACID compliance, rich SQL support, and decades of battle-tested reliability. Connect it to Actionist and your agents can insert rows, run custom queries, react to table changes via LISTEN/NOTIFY, wrap multi-step writes in transactions, and sync data across your entire tool stack — all without touching a SQL client. Whether you're automating ETL pipelines, keeping CRM records in sync, or building real-time event-driven workflows, PostgreSQL gives your agents a durable, queryable backbone.

Churn signal to CSM in 60 seconds

When a support email arrives flagging a customer's pain point, the agent looks up the account's health score, contract value, and open tickets in PostgreSQL in one read — then logs the escalation flag back into the `account_health` table so nothing falls through the cracks. A Slack message lands on the CSM's desk with every relevant number before the customer has sent a follow-up, and a 30-minute check-in call is blocked in Google Calendar automatically. No manual CRM trawling, no copy-pasting between five tabs.

Connect

How to plug PostgreSQL into Actionist

Pick the connection method that suits your environment.

The fastest path. Install one of PostgreSQL's official MCP servers from the Apps library and your agent queries tables, runs custom SQL, and inspects schemas through a permissioned connection — no credentials stored in plain text, no port forwarding.

1
Open the Apps tab

Find PostgreSQL in the Apps library and click Connect. MCP is selected by default — choose your preferred MCP server (e.g. the official waystation postgres server).

2
Provide your connection string

Enter your PostgreSQL connection string (e.g. postgres://user:password@host:5432/dbname). The MCP server holds this credential; Actionist never stores it directly.

3
Test the connection

Actionist runs a read-only `SELECT 1` to verify the handshake. You'll see your schema listed in the connection panel when it succeeds. You're ready.

FAQs

Questions about PostgreSQL + Actionist

How do I connect PostgreSQL to Actionist?
Open the Apps tab, find PostgreSQL, and click Connect. The recommended path is via an MCP server — choose from the official postgres MCP servers listed in the connection panel, enter your connection string (host, port, database, user, password), and Actionist runs a read-only verify query to confirm. The whole setup takes under two minutes. For direct connections without MCP, enter your credentials manually and enable SSL if your host requires it.
What credentials does Actionist need to connect to my PostgreSQL database?
You need a host (or domain name), a port (default 5432), a database name, a username, and a password. Your PostgreSQL user needs at minimum SELECT permission on the tables you want to read, and INSERT / UPDATE / DELETE on any tables the agent writes to. For trigger-based workflows, the user also needs TRIGGER permission and the ability to call pg_notify. Restrict the user to the specific schemas the agent needs — avoid connecting as a superuser.
Can my agent combine PostgreSQL with other apps in the same workflow?
Yes — PostgreSQL works as both a data source and a destination alongside any other app in Actionist. Common patterns include reading from PostgreSQL and writing to Slack, Google Sheets, or HubSpot; reacting to a HubSpot or Stripe event and inserting a row into PostgreSQL; and using PostgreSQL as the state store for a multi-step orchestration that spans four or five apps. The agent handles the data mapping between systems automatically.
How does the Insert / Update / Delete trigger work — does it poll the database?
Insert, Update, and Delete triggers use PostgreSQL's native LISTEN/NOTIFY mechanism. When you connect the trigger, Actionist creates a trigger rule in your database that calls pg_notify on the specified event. The agent maintains a persistent LISTEN connection so it fires within milliseconds of the event — no polling interval. New Row and New or Updated Row triggers do poll on a schedule (configurable), which is the fallback for databases where you cannot create trigger rules.
How do I avoid writing duplicate rows when a trigger fires more than once?
Use an upsert pattern: pass your natural unique key (e.g. `external_id`) to the New Row action and enable conflict handling so the agent runs INSERT ... ON CONFLICT DO UPDATE instead of a plain INSERT. For trigger-based workflows that might re-fire on retry, add an `idempotency_key` column to your target table and include it in the conflict target. This ensures a re-run updates the existing row rather than inserting a duplicate.
Can the agent run complex SQL queries involving JOINs, CTEs, or window functions?
Yes. Use Find Rows via Custom Query or Find Row via Custom Query and write any valid PostgreSQL SELECT — JOINs, CTEs, window functions, PostGIS expressions, and jsonb operators all work. The agent returns the result set as structured data your workflow can iterate over or pass downstream. For writes, use Single Query with a raw SQL action to execute INSERT ... SELECT, UPSERT, or any DML that goes beyond the standard action options.
What is the Transaction batching mode and when should I use it?
Transaction mode wraps all SQL statements in a single BEGIN / COMMIT block. If any statement fails, the entire batch rolls back — no partial writes reach the database. Use it any time your workflow makes multiple writes that must succeed or fail together: order placement (insert order + deduct inventory + create payment intent), fund transfers (debit + credit), or multi-table migrations. For independent writes where partial success is acceptable, use Independently mode instead, which sends each statement as a separate transaction.
My NUMERIC or BIGINT columns are losing precision in downstream steps — how do I fix it?
JavaScript's number type can only represent integers up to 2^53 - 1 (Number.MAX_SAFE_INTEGER). If your BIGINT or high-precision NUMERIC values exceed that limit — common with Unix epoch microseconds, crypto amounts, or 20-digit IDs — switch the Output Large-Format Numbers As setting to Text. The agent returns those column values as strings, preserving every digit. Parse them back to a number only where the downstream system genuinely needs arithmetic; for display or key-matching purposes, keep them as strings.
