Review: check existency of table for -t option (pg_dump) when pattern...

https://commitfest.postgresql.org/6/201/

Patch looks good and is helpful in some usecases. I found and fix some typo (new
version in attach), but patch shows some inconsistent output:
% pg_dump -t 'aaa*'  postgres
pg_dump: No matching tables were found
% pg_dump -t 'aaa*' --strict-names postgres
pg_dump: Table "aaa*" not found.

In second case error message is obviously worse.
