This patch fixes a bug in the error message emitted by pg_restore on an
incorrect -F argument: write_msg() expects its first parameter to be a
"module name", not the format string. Patch applied to HEAD. Is this
worth backporting?
BTW, is there a reason that pg_restore seems to accept 'f', 't', or 'c'
parameters to this argument, but the documentation only documents 't'
and 'c'?
