Mutar consulta de banco postgree p/ MySQL

Olá pessoal,

Estou transformando o funcionamento de um sistema de ponto eletrônico, para trabalhar com MySql ao invés de Postgree.

Gostaria de saber como seria a consulta equivalente em MySQL

$chaves = "SELECT pt.tgargs FROM pg_class pc,
 pg_proc pg_proc, pg_proc pg_proc_1, pg_trigger pg_trigger,
 pg_trigger pg_trigger_1, pg_proc pp, pg_trigger pt
 WHERE pt.tgrelid = pc.oid AND pp.oid = pt.tgfoid
 AND pg_trigger.tgconstrrelid = pc.oid
 AND pg_proc.oid = pg_trigger.tgfoid
 AND pg_trigger_1.tgfoid = pg_proc_1.oid
 AND pg_trigger_1.tgconstrrelid = pc.oid
 AND ((pc.relname = '$tabela')
 AND (pp.proname LIKE '%%ins')
 AND (pg_proc.proname LIKE '%%upd')
 AND (pg_proc_1.proname LIKE '%%del')
 AND (pg_trigger.tgrelid=pt.tgconstrrelid)
 AND (pg_trigger_1.tgrelid = pt.tgconstrrelid))";
