* fix(relay): skip boot-time DDL when the catalog already has the object CREATE INDEX IF NOT EXISTS and ALTER TABLE ADD COLUMN IF NOT EXISTS take their relation lock before the server evaluates the existence test, so a boot on an already-migrated database still joins the lock queue. Relation locks are granted in queue order, so every writer queues behind it. The shared runner now asks pg_catalog whether the index or column is already there and skips the statement when a row comes back, and 55P03 is no longer retried by default: with the pre-check ahead of it, a lock timeout means the object is genuinely missing and each retry re-enters the queue. Push keeps the old retry behind an explicit option. * fix(relay): tie the index pre-check to its table and fail on an unreadable target Three defects found in review of the auth reference implementation: - The catalog query matched an index by name inside the table's namespace without checking it belonged to that table. Index names are unique per schema, not per table, so a same-named index on a sibling table answered yes and the real index was skipped forever. Added i.indrelid = t.oid. - Lock-target derivation read a keyword sitting in an identifier position as the object name: CREATE UNIQUE INDEX CONCURRENTLY ON t(c) yielded the name CONCURRENTLY, and ADD COLUMN IF NOT EXISTS with no column yielded IF. A wrong target is worse than none, so keywords are now excluded and an index or column statement whose target cannot be read throws at boot with the statement text instead of falling through to the lock path. - A concurrent-create collision retried the CREATE INDEX, taking SHARE on the table again for an object another director had just finished creating. The catalog is re-asked instead and a present object counts as skipped. * fix(relay): pre-check constraint swaps so a warm boot sends no DDL at all The two ALTER TABLE constraint statements were the last lock-taking statements without a pre-check, so every boot still took ACCESS EXCLUSIVE on relay_region_rehome_attempts twice. A lock target now carries the catalog answer that means there is nothing left to do. ADD CONSTRAINT skips when pg_constraint already names it; DROP CONSTRAINT IF EXISTS is the inverse and skips when it does not, because nothing to drop is nothing to do. The match is by name only: the CHECK body is generated from RELAY_REGIONS, so comparing it would re-run the swap on every region change. Changing a definition under the same name is an operator migration, and the rule comment beside SCHEMA says so. A bare DROP CONSTRAINT gets no target and throws at boot, because skipping it would swallow the undefined_object the server is supposed to raise. The census invariant is now that every lock-taking statement has a pre-check, with no exceptions, and the warm-boot Postgres test asserts zero statements sent rather than two. * fix(relay): refuse a multi-action ALTER TABLE instead of pre-checking its first action `ALTER TABLE t ADD COLUMN IF NOT EXISTS a TEXT, ADD COLUMN IF NOT EXISTS b TEXT` derived the target for `a` alone, so once `a` existed the whole statement was skipped and `b` was never added. The first subcommand parses, so neither the parse throw nor the census caught it. A lock-taking ALTER TABLE with a comma outside parentheses, quotes and comments now throws at boot. One action per statement, or no pre-check is possible. Commas inside a parenthesised type, a CHECK body, a quoted default or a comment are unaffected, and push's 18 statements still parse. * fix(relay): strip every comment before classifying, fold catalog names, count brackets Four findings from the bot reviews on #21147: - A comment between two keywords (ALTER TABLE t ADD /* note */ COLUMN c TEXT) was invisible to both the classification regexes and the must-parse shapes, so the statement got no target AND no throw and ran with no pre-check. Every comment is now stripped quote-aware before classification, nested block comments included. The server is still sent the original text. - hasTopLevelComma counted parentheses but not square brackets, so ADD COLUMN c bigint[] DEFAULT ARRAY[1, 2] read as two subcommands and failed the boot. - bareIdentifier split a qualified name on '.' regardless of quoting, so "a.b" became b", and it kept the written case while Postgres folds an unquoted identifier to lower case before storing it in relname, attname and conname. The name is now tokenised quote-aware and folded, with the qualified table text still passed to to_regclass as written. - sqlWithoutLeadingComments is renamed sqlWithoutComments to match. Relay's 74 statements and push's 18 all still parse, and no relay target name changed: every identifier there was already lower case. * fix(relay): treat a dollar-quoted body as opaque in both scanners A comment marker, comma, parenthesis or bracket inside `$$...$$` or `$tag$...$tag$` is text. The closing delimiter has to match the opening tag exactly, so an inner `$$` inside a `$tag$` body is more text rather than the end, and a tag cannot start with a digit, which keeps a `$1` placeholder from reading as an opener. Relay's pg_stat_statements DO block is the only dollar-quoted statement in the schema, and it now survives the stripper byte-identical. A test asserts that against the real statement.
