PostgreSQL database documentation - SQL queries, database design, administration, performance tuning, and advanced features. Use when working with PostgreSQL databases, writing SQL, or managing database systems.
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
# Postgresql Skill Comprehensive assistance with postgresql development, generated from official documentation. ## When to Use This Skill This skill should be triggered when: - Working with postgresql - Asking about postgresql features or APIs - Implementing postgresql solutions - Debugging postgresql code - Learning postgresql best practices ## Quick Reference ### Common Patterns **Pattern 1:** 32.1. Database Connection Control Functions # 32.1.1. Connection Strings 32.1.2. Parameter Key Words The following functions deal with making a connection to a PostgreSQL backend server. An application program can have several backend connections open at one time. (One reason to do that is to access more than one database.) Each connection is represented by a PGconn object, which is obtained from the function PQconnectdb, PQconnectdbParams, or PQsetdbLogin. Note that these functions will always return a non-null object pointer, unless perhaps there is too little memory even to allocate the PGconn object. The PQstatus function should be called to check the return value for a successful connection before queries are sent via the connection object. Warning If untrusted users have access …

How to install
mdr add aiskillstore/marketplace/postgresql@sha256:9c184adb1cd69d5eThe line at the top of this page pins the label git:20260113.222b7de, 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.
