discourse core does not use the vector extension, so the pgvector image is unnecessary. Switch db to pgautoupgrade/pgautoupgrade:17-trixie, which handles major-version upgrades (old binaries, initdb, pg_upgrade) itself. pgautoupgrade assumes the old cluster's install user (oid 10) equals POSTGRES_USER and fails pg_upgrade otherwise (issue #115). A thin wrapper entrypoint detects the old install user when an upgrade is pending and exports POSTGRES_USER so pgautoupgrade matches it. Replaces the 64-line hand-rolled pg_upgrade entrypoint.
