problems

Dear Sir.

I'm using one FreeBSD 4.6 with PostgreSQL 7.2.1_1, apache2 and
php4-4.2.1_1 .

The pgsql is running ok, but when the user pgsql try to create a
database, the error message is:

> createdb example
ERROR: CREATE DATABASE: permission denied
createdb: database creation failed

the directory structure is:

drwxr-xr-x 4 pgsql pgsql 512 Aug 6 19:50 .
drwxr-xr-x 29 root wheel 1024 Aug 6 16:45 ..
-rw-r--r-- 1 pgsql pgsql 323 Jun 21 18:40 .cshrc

-rw-r--r-- 1 pgsql pgsql 2998 Jun 21 18:40 post-install-notes

the data dir structure is:

drwx------ 6 pgsql pgsql 512 Aug 7 20:08 .
drwxr-xr-x 4 pgsql pgsql 512 Aug 6 19:50 ..
-rw------- 1 pgsql pgsql 4 Aug 6 14:08 PG_VERSION

-rw------- 1 pgsql pgsql 26 Aug 7 20:08 postmaster.opts
-rw------- 1 pgsql pgsql 46 Aug 7 20:08 postmaster.pid

The file pg_hba.conf (last 4 lines) is:

local all trust
host all 127.0.0.1 255.255.255.255 trust
host all X.Y.Z.W 255.255.255.0 password
host database X.Y.Z.S 255.255.255.0 crypt

What I need to solve this problem ?

Thanks.
