I'm having no problems using the 7.3b libpq against a 7.2.1 server, so
far.
The 7.3 psql is pretty much unusable tho against a 7.2 server. It
generates a parser error in the server as soon as it starts up and
connects:
DEBUG: BackendStartup: forked pid=4881 socket=8
postmaster child[4881]: starting with (postgres -d2 -v131072 -p nocprovider )
DEBUG: InitPostgres
DEBUG: StartTransactionCommand
DEBUG: query: select getdatabaseencoding()
DEBUG: ProcessQuery
DEBUG: CommitTransactionCommand
DEBUG: StartTransactionCommand
DEBUG: query: SELECT usesuper FROM pg_catalog.pg_user WHERE usename = 'prashanth'
ERROR: parser: parse error at or near "."
DEBUG: AbortCurrentTransaction
and then goes steadily downhill from there.
thanks,
