Re: [HACKERS] pg_dump -t broken for mixed case table names in beta3?

Unless I'm missing something, pg_dump is not allowing selective dump of
a table where the table name is mixed case. The -t switch still works
for lower case. Even though quotes weren't previously needed on the
pg_dump command line, I tried that with no better luck.

You do it like this:

$ pg_dump -s -t '"DbTranLogRecord"' dtr

A bit ugly but the conflict between shell and SQL quoting rules
sometimes forces us into compromises :-(

Perhaps it's worth having an example for this in the pg_dump man page?

Thanks much; it might have been a while before I tried that nested
quoting technique. I think it's worth documenting. Would you like me
to try to put a doc patch together, or would it be better for someone
else to do so?

You do it like this:

$ pg_dump - s - t '"DbTranLogRecord"' dtr

A bit ugly but the conflict between shell and SQL quoting rules
sometimes forces us into compromises :- (

Perhaps it's worth having an example for this in the pg_dump man page?
