I figure the best thing to do is to upgrade postgres 8.4 (not 8.1 as previously mentioned) to 9.2 on this centOS6.4
server,so it's version matches the other server. I searched for some time on how to do this and every tutorial does it
alittle different and each has different steps that the others do not have. Is there a clear step by step procedure to
dothis upgrade?
Thanks

A dump from 9.2 is no sure thing to restore into an 8.1 database; there may be SQL syntax in it that 8.1 doesn't
understand. Have you checked for errors during the restore?
