Sequences in DB/pgsql (once again)

Greetings! Well, I made an update of PEAR and found sequence implementation... First of all, I honestly don't think that if ($ondemand && DB::isError($result) && $result->getMessage() == "DB Error: ERROR: db_seq_test.nextval: sequence does not exist\n") { is the intended behaviour... ;] Relying on error messages' format is probably a Bad Thing itself... As for 'db_seq_{$seq_name}' - I don't think that prepending *anything* to table (or sequence) name is good. The reasons are simple - prefixes are usually used for hiding something or grouping (if a table name begins with 'pg_' in Postgres - it is a system table, if it begins with 'pga_' - it is a PgAccess table and is not shown in PgAccess). Besides, 'db_' prefix is misleading. -- Yours, Alexey V. Borzov, Webmaster of RDW
