Dear All,
I have upgraded Postgresql from 7.3 to 7.4.
Starting pg brings error:
The database is in an older format that cannot be read by version 7.4 of
PostgreSQL

dpkg-upgrade postgresql fails
I tried postgresql-dump. While dumping it brings the following error:
FATAL: unsupported frontend protocol
However the dump file is generated.
Does this error means that dump file can not be used or it can be ignored?
Thanks a lot
Oleg
