Ok, I have an Apache, PHP, MySQL, and Postgresql installation.
If I start postgresql from the 7.1.3 version that was installed by RPM's then phpPgAdmin and my internal functions work.
If I start postgresql from the 7.1.3 version that I built from the source tree then phpPgAdmin as well as my internal functions tell me that it is a reference to an undefined function pg_connect().
In either of the above cases I can use psql from the command line and the system works fine.
I noticed that in the source directory there were subdirectories under directory interfaces. These directories are perl5, odbc, and python etc.
Any help or ideas, please
John
