[Mapserver-users] postgis data statement

[Gernot Katzlberger]

hi pericles, zamil & list,

my postgis data statement works now in Mapserver, but it needs ~5 min to
render it. when I start it, 99% of my system cpu usage is occupied by one
process:

postgres: {user} {database} 127.0.0.1 FETCH


when I execute it in psql it works in milliseconds.
mapserver and postgresql/postgis are on the same server. I also checked the
user privileges.

many thanks for your help,

gernot

Gernot,

Zamil is correct.  If the SQL statement worked in psql (or some other
frontend), it should work in MapServer.  If not, the first place to check
would be your PostgreSQL configuration and permissions.  If your database
is running remotely you might want to check that you have configured
postgres to accept remote connections.  If that is the case, try
connecting as postgres (or whatever pg admin account you created).  If it
works, read the PostgreSQL docs for adding users.  Sometimes it's just a
matter of giving an existing database user select privileges on your
postgis tables.  I've posted other messages to related questions in the
past.  Have a look at the MapServer-users archive as I don't have a
browser open.

Cheers!

proper permissions set for the database. Does the user/password that you
supply to your connection string work? Is it a TRUSTed user? Maybe you need
to give the box that mapserver is installed on TRUSTed access to that
postgres db. Take a look at your pg_conf.hba file (i think that is what it
is called).
