PG_OPEN(cDsn) -> integer handle, -1 on failure
PG_CLOSE(nH) -> NIL
PG_QUERY(nH, cSQL [, aArgs]) -> array of { col => val } hashes
PG_EXEC (nH, cSQL [, aArgs]) -> rows affected, -1 on error
PG_LAST_ERROR(nH) -> last error string
Backed by github.com/jackc/pgx/v5/pgxpool, which is already in Five's
indirect dep tree (pgserver uses pgproto3 from the same repo). Pool
limits: MaxConns 8, MinConns 1, 5-min idle. Query timeout is capped at
30s so a runaway query can't pin a goroutine forever.
aArgs uses standard Postgres $1/$2/... placeholders — pgx parameter
binding prevents SQL injection. Never concatenate user input into cSQL.
Smoke-tested with app/pg_test.prg: bad DSN returns -1 cleanly (no
panic), the error path prints the expected fallback message, and the
real round-trip path is wired so setting LABDB_DSN to a live database
exercises SELECT + parameter binding + multi-row return without any
further code change.
