I don’t know a lot myself, but postmaster should be running, and you may need to play with:

postgres.conf

pg_hba.conf

pg_ident.conf

Sincerely,
r.

I am new to PostgreSQL but have gotten to the point where I have postmaster running as a service on Windows 2000 and can connect to the server by typing 'psql mydb'.  I cannot however get a Perl/DBI connection to my database.  I have tried both DBD::Pg with ActiveState Perl 5.6.1 and DBD::PgPP with ActiveState Perl 5.8.0.  I installed PostgreSQL 7.3.1 with cygwin.  The error messages I get with each type of connection are listed below:

 

(Perl 5.6.1 and DBD::Pg)

DBI->connect(dbname=mydb) failed: could not create socket: An address incompat
 at x.pl line 5equested protocol was used.
could not create socket: An address incompatible with the requested protocol was
 at x.pl line 5.

 

(Perl 5.8.0 and DBD::PgPP)

DBI->connect(dbname=mydb) failed: Couldn't connect to /tmp/.s.PGSQL.5432:  at
c:/perl58/site/lib/DBD/PgPP.pm line 124
 at x.pl line 5

I am really more interested in getting the connection to work with Perl 5.6.1 but have verified that /tmp/.s.PGSQL5432 exists and seems to have the right permissions.

pg_hba.conf defines the limitations to access and authenticate with the
database - that's the most likely of the three to need editing in your
case.

I've never used the Windows version so I don't know if it supports local
socket access, but for TCP access you need to ensure you are running
PostgreSQL with the -i switch.

Is there a Windows equivalent to "netstat"?  You might check to see
whether the DB is listening.

Cheers,
                    Andrew.

For version of server use:
select version();

For version of psql use:
psql -V
