Create a PostgreSQL materialization to stream Estuary collections into PostgreSQL tables. Use when setting up PostgreSQL as a destination for captured data. Use when user says "send to Postgres", "materialize to PostgreSQL", "Postgres destination", or "load into Postgres".
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Create PostgreSQL Materialization Create a PostgreSQL materialization using flowctl to stream data from Estuary collections into PostgreSQL tables. **Applies to**: materialize-postgres (all variants: vanilla, RDS, Aurora, Cloud SQL, Supabase, AlloyDB, Neon) ## Step 0: Load Connector Documentation Before proceeding, fetch the official connector docs for prerequisites, config reference, and setup instructions. **Load the docs page:** https://docs.estuary.dev/reference/Connectors/materialization-connectors/PostgreSQL/ Use WebFetch to load this page. It covers: - Prerequisites (user creation, permissions, schema setup) - Full config property reference - SSH tunnel configuration - SSL configuration - Advanced options (delta updates, hard deletes, sync schedule) **Search Kapa for tribal knowledge** (if the Estuary MCP is configured): ``` Search kapa ai knowledge sources for "materialize postgres common issues" ``` If Kapa MCP is not configured, the user can set it up: https://docs.estuary.dev/features/mcp-integration/ This skill provides the **flowctl workflow** and **troubleshooting** that docs don't cover. ## Step 1: Gather Requirements …

How to install
mdr add estuary/agent-skills/materialize-postgres-create@sha256:1395af55e92e153fThe line at the top of this page pins the label git:20260505.8873932, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
