Subject: Throw an error when using -C and -1 at the same time in pg_restore.
X-Git-Url: http://git.postgresql.org/gitweb/static/gitweb.js?a=commitdiff_plain;h=5b5f062f0c46dca28f4b51fc760e831a4c8ae467;p=users%2Fbernd%2Fpostgres.git

Throw an error when using -C and -1 at the same time in pg_restore.

It's not possible to do CREATE DATABASE inside a transaction, so previously
we just got a server error instead.

Backpatch to 8.2, which is where the -1 feature appeared.
