Re: Cannot connect to one specific postgres database on a server

When you say "The site that is using the database is also running fine",
Do you mean users are accessing
that database? If so, that check the port # you are using to connect.

You might also try adding a new server connection to that database in
pgadmin.

postmaster is the postgresql process that is needed to access the
database.

Telnet to the server and do
ps -ef | grep postmaster

You should see something like
admin 2986 1 0 Jan12 ? 00:00:00
/home/pgsql/postgresql-8.0.6/bin/postmaster

You will have a process for each database on a separate port.

If all postmaster(s) are running, then perhaps someone or
something(gremlins) :) has modified the
pg_hba.conf file in the $PGDATA directory?

I can telnet to the database and query the database.... The site that is
using the database is also running fine

Not sure what postmaster is.... How can I check if its running? I did a
google search for it, but not sure how to check it on my postgres db
server

I don't get any errors using telnet ... I can access the db every other
way it seems, just using postgres

If I restore/rebuild the db, will that cause the database to go down at
all? I will try anything to get pgadmin working with the db... it makes
my life SOOO much easier!



Thanks very much for taking the time to help me with this issue! Much
appreciated!

Matt

I cannot tell you what is specificially wrong, but try the following:

Can you telnet to that database and query?

Is the postmaster running for that database?

Do you get any errors returned when you try to connect via telnet? What
are they?

Is it possible your database is corrupted and you need to
restore/rebuild?

Subject: [pgadmin-support] Cannot connect to one specific postgres
database on a server
Hello,
I am having trouble connecting to one specific database on my server. I
can connect to the server via pgadmin and have pgadmin display 7 or 8
databases I have running on the server. I can successfully connect to
all of the databases except one. This particular database I am trying to
connect to will just cause pgadmin to hang/crash

I have been using pgadmin for over 2 years to connect to this particular
database that wont connect now. This just started happening a week ago
and is frustrating me so bad! I have installed/reinstalled/uninstalled
about every version on pgadmin with no success. I restarted postgres on
the server with no success...

My server is running linux, and I am using windows version of pgadmin...

I WOULD REALLY APPRECIATE ANY HELP!!! THANKS SO MUCH!!!
