[COMMITTERS] pgsql: Increase SCRAM salt length

Increase SCRAM salt length The original value 12 was set based on RFC 5802 for SCRAM-SHA-1, but RFC 7677 for SCRAM-SHA-256 uses 16, so use that. (This does not affect the validity of already stored verifiers.) Discussion: https://www.postgresql.org/message-id/flat/12cc9297-7e05-932f-d863-765e56
