> It's not a bug, but it's kind of an annoying situation. The double quotes on the command line just delimit the name
ofthe table, but the shell strips them off (as you would expect), so pg_dump just gets the bare name. You have to add
separate,escaped double-quotes, since the table name requires them:
Another way with slightly fewer keystrokes is
pg_dump ... --table '"TABLE2"'
Of course, if you're also in the habit of putting single-quotes in
your table names, that'll still need some work. The main point is
that there are two layers of quoting that you have to deal with:
the shell's, and then SQL's.
