Error connecting database
Connection to database failed
connectDB() failed: Is the
postmaster running and
accepting TCP/IP (with -i)
connections at 'localhost' on
port '5432'?
This usually occurs because the "postmaster" (the postgreSQL backend) was not
started with the -i option.  Usually just adding -i to
the command line that starts the postmaster and restarting will fix this.
 
ftp://ftp.flex.ro/pub/pgaccess 
is one place that you can download precompiled libpgtcl libraries for
PgAccess.libpgtcl not found
PgAccess requires a library of functions named libpgtcl.  This
should be available with the postgreSQL distribution, and is usually placed in
the correct location when installing postgreSQL.  First check that there is a
file named libpgtcl.so (perhaps with a number appended - or
libpgtcl.dll on Windows systems) on your
system.  If not, you will have to download and perhaps compile this library.
