Overview
Updates pg_clickhouse managed Postgres extension docs to v0.3.2, mainly in
reference.mdandintroduction.md.Getting started / install: Docker image tag moves from
:18to:19; Debian/Ubuntu examples usepostgresql-server-19instead ofpostgresql-server-18.Foreign server (
CREATE SERVER): Documents new connection options—compression(binary driver),min_tls_version, andsecure(auto/on/offwith port defaults).Pushdown & compatibility: Adds
regexp_matchpushdown (extractGroups/extractAll+arraySlice). Rewrites the regex section: Postgres→ClickHouse flag mapping table (m,n,p,w, etc.), newline/line-ending behavior comparison tables, and notes that unsupported flags block pushdown. Documentsregexp_matchreturningNULLvs ClickHouse empty arrays (COALESCE(..., '{}')). External Postgres doc links switch from version18tocurrent.Reviewed by Cursor Bugbot for commit 118619b.
