Postgres 6.4.2 connection problem
REGARDING Postgres 6.4.2 connection problem
We configured an external drive with postgres 6.4.2 such that we could
run postgres/connect via psql, etc.
Upon connecting the external drive to a different machine (same OS, Sun
Solaris 2.5.1 and configuration/architecture), we changed the appropriate
environment variables and updated the pg_hba.conf file with a new host
entry with the IP of the machine. The postmaster process starts up on the new
machine however we are receiving the following error upon trying to
connect to it via psql:
Connection to DB Template1 failed
Connect DB(): getprotobyname failed
Any idea what causes this error message?
Thanks,
Andy

Just what it says: getprotobyname() failed --- there is only one
place in libpq that can generate that message.
Now, *why* it failed is a more interesting question; that really
shouldn't happen in a machine with functioning TCP/IP support.
My guess is that this new machine is not as close to being an
identical platform as you thought, and that you need to rebuild
the Postgres libraries and binaries from source.
It's also possible that there's something wrong with the
/etc/protocols file on the new machine, but if that were the
case then very little would be working...
