Re: Dump file created with pg_dump cannot be restored with psql

Oh, sorry. I mixed up dumps...

I am migrating from mysql and by mistake I tried to apply dump from "mysqldump --compat=postgresql" that was named very similar to dump of finally converted database produced by pg_dump (for the purpose of copy from test to main server). Bash comletitions and then bash history (when I was reproducing problem before mailing here) made malicious joke on me. :)

Sorry for inattention. And thank you for your answer. I found my mistake when I was looking for the exact command.
