  ### Now we need to install the perl interface for postgresql.
gmake -C src/interfaces/perl5 install
cd /usr/local/src/postgresql-7.1.3/src/interfaces/perl5
perl Makefile.PL
make 
  ### Uncomment the next line if you want to test it. 
##  su -c 'make test' postgres
make install

  ### Change ownership of all files to the user postgres.
chown -R postgres /usr/local/pg713

  ### Initialize the database. 
su -c '/usr/local/pg713/bin/initdb -D /usr/local/pg713/data' postgres

  ### Start the database server. 
su -c '/usr/local/pg713/bin/pg_ctl -o " -p 6000 " -D /usr/local/pg713/data -l logfile start' postgres

  ### The interfaces for perl, tcl, and pl/pgsql should have been created. 
  ### Now add them. 
  
su -c 'createlang -p 6000 plpgsql template1' postgres
su -c 'createlang -p 6000 pltcl template1' postgres

### Now assuming you have perl 5.6.1 installed correctly.
rm -f /usr/local/pg713/lib/libperl.so
ln -s /usr/lib/perl5/5.6.1/i686-linux/CORE/libperl.so \
  /usr/local/pg713/lib/libperl.so
su -c 'createlang -p 6000 plperl template1' postgres

  ### If it worked out correctly, any new database will copy itself from 
  ### template1 and have perl, tcl, and pl/pgsql. 

  ### Now additional stuff.
su -c 'createdb -p 6000 postgres' postgres
