PostgreSQL integration
Turn Postgres into dashboards and alerts — with AI.
Connect your PostgreSQL database and start asking questions in plain English. Fastero generates optimized SQL, returns results as charts and tables, and lets you save anything as a dashboard or automated alert. Works with any Postgres-compatible database.
What you can do
Query, visualize, and monitor — all from Postgres.
Natural language to SQL
Ask questions in plain English and get PostgreSQL queries generated against your schema. Fastero understands your tables, foreign keys, indexes, and relationships — no manual mapping required.
AI-generated dashboards
Save any query result as a dashboard panel. Combine multiple queries into a single view with charts, tables, and KPI cards. Share with your team via a link or embed in your app.
Automated alerts and triggers
Set up SQL-based alerts that run on a schedule. When a query result crosses a threshold — revenue drops, churn spikes, orders stall — get notified in Slack, email, or a webhook.
How it works
Three steps. Under five minutes.
Add your connection
Provide your Postgres connection string or host/port/database details. Fastero reads your schema metadata including tables, columns, foreign keys, and indexes. Read-only access — we never write to your database.
Ask questions in plain English
Type a question like "top 10 customers by lifetime value" and get a PostgreSQL query generated, executed, and visualized in seconds.
Save as dashboard or trigger
Pin results to a dashboard for ongoing visibility, or create a trigger that runs the query on a schedule and alerts you when something changes.
PostgreSQL-native
Built for PostgreSQL.
Fastero generates queries that use PostgreSQL-specific syntax and features. No generic SQL that breaks on execution.
CTEs and recursive queries
Window functions (ROW_NUMBER, LAG, LEAD, etc.)
JSONB operators and path expressions
date_trunc, generate_series, and interval arithmetic
Materialized views and index-aware optimization
Schema and foreign key relationship navigation
Also works with Postgres-compatible databases
Supabase, Neon, CockroachDB, Amazon Aurora PostgreSQL, Google AlloyDB, TimescaleDB, and any database that speaks the PostgreSQL wire protocol.
Example queries
Questions people actually ask their Postgres data.
“Top 10 customers by lifetime value”
“Orders with no payment in 48 hours”
“Daily signup trend with 7-day moving average”
“Revenue by plan tier, last 30 days”
“Users who were active last week but not this week”
“Average response time by support agent this month”
Frequently asked questions
Common questions about the PostgreSQL integration.
Is the connection read-only?
Yes. By default, Fastero connects with a read-only role and only executes SELECT statements. We recommend creating a dedicated Postgres user with SELECT-only permissions on the schemas you want to query. Fastero will never run INSERT, UPDATE, DELETE, or DDL statements against your database.
Is SSL required?
Yes. Fastero always connects over SSL/TLS encryption and rejects unencrypted connections. Your database credentials are encrypted at rest using AES-256. We support both self-signed certificates (with CA verification) and certificates from public authorities.
Which Postgres-compatible databases work?
Fastero works with any database that speaks the PostgreSQL wire protocol. This includes Supabase, Neon, CockroachDB, Amazon Aurora PostgreSQL, Google AlloyDB, TimescaleDB, and Citus. If you can connect with psql, you can connect with Fastero.
