Postgres behaviour worth checking before relying on it — type choices, index kinds and their costs, reading EXPLAIN output, isolation levels and lock behaviour during DDL, and row-level security. Use when the project runs on Postgres (including Postgres-backed services) and a decision depends on what the engine actually does: picking a column type, adding an index, changing isolation, or writing and debugging an RLS policy. Not for engine-neutral modelling decisions, and not for the…
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
# Postgres Most Postgres surprises come from defaults: the default isolation level, the default lock an `ALTER TABLE` takes, what happens to a table with RLS enabled and no policy. Check the default before designing around what you assume it is. ## When this fires The project is on Postgres and the answer depends on engine behaviour rather than on modelling. It does not fire as a tour — read the section the decision needs. It does not fire for another engine, and Postgres-compatible services differ in what they permit, so confirm rather than assume. ## Procedure 1. **Establish what you are actually talking to.** `select version();` and list the installed extensions before writing DDL that depends on one. Major versions differ in defaults and in available syntax, and an extension you assume is present (`citext`, `pg_stat_statements`, `pgcrypto`, `postgis`) is either installed or it is not. If the version is unknown, prefer the long-standing form of a feature over the newest one. 2. **Choose types on meaning.** `text` for strings unless a length is a real constraint worth enforcing; timezone-aware timestamps for instants and plain `date` for dates; `numeric` for …

How to install
mdr add nahid-sparktales/agent-dispatcher/postgres@sha256:73953c7fb93d3c97The line at the top of this page pins the label git:20260919.a0d4f55, 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.
