Hello Sir,
The following error is comming when i want to get into
the database.
$./psql
psql: connectDBStart() -- connect() failed: No such
file or directory
Is the postmaster running locally
and accepting connections on Unix socket
'/tmp/.s.PGSQL.5432'?
if i type the following command i am getting the
following :
$ pg_ctl status -D /home1/market/postgres/data
pg_ctl: postmaster is running (pid: 1295)
Command line was:
/home1/market/postgres/postgresql-7.2.3/bin/postmaster
'-i' '-D' '/home1/market/postgres/data'
when i type following command then this error is
comming:
$ createdb stu
psql: connectDBStart() -- connect() failed: No such
file or directory
Is the postmaster running locally
and accepting connections on Unix socket
'/tmp/.s.PGSQL.5432'?
createdb: database creation failed
If type another command like this then :
$pg_ctl start -D /home1/market/postgres/data
pg_ctl: Another postmaster may be running. Trying to
start postmaster anyway.
Lock file "/home1/market/postgres/data/postmaster.pid"
already exists.
Is another postmaster (pid 1295) running in
"/home1/market/postgres/data"?
pg_ctl: cannot start postmaster
Examine the log output.
I had examined the output then following is there
Lock file "/home1/market/postgres/data/postmaster.pid"
already exists.
Is another postmaster (pid 1295) running in
"/home1/market/postgres/data"?
