I am thinking same too. Maybe somebody will be happy, bacause they can
to write SHOW TABLES, but they will be unsatisfied when will try to
write SHOW TABLES WHERE ... so only full support of MySQL syntax has
sense. Some only text version of SHOW TABLES command isn't sense for
me - it can do only more problems with incompatibility.
Still I thinking about top level hook - so these and similar commands
can be implemented inside external modules.
I have a different opinion on DESCRIBE command. This really can help.
But it must not be a command. "describe" function is enought -
select describe(oid);
select describe_table(name);
