Tom Lane-2, Thanks for your reply. This is my first error Initially i got error *plpgsql.so file missing*, then created symbolic link for /usr/local/pgsql/lib from /usr/lib/postgresql/lib First error checks for plpgsql.so files in /usr/lib/postgresql/lib. So i created symblink. Second error looks for $libdir/ltree. But there is no such libdir environment variable in .bash_profile. Notice: type 'ltree' is not yet defined *Error : could not access file "$libdir/ltree": no such file or directory* [postgres@oracle bin]$ pg_config --libdir /usr/local/pgsql/lib [postgres@oracle bin]$ pg_config --pkglibdir /usr/local/pgsql/lib But i have ltree directory in the following path I have all the file here like tsearch2 and ltree. How can i map this dir to libdir? [postgres@oracle contrib]$ pwd /usr/local/src/postgresql-7.4.23/contrib I set environment variables in .bash_profile LD_LIBRARY_PATH=/usr/local/pgsql/lib export LD_LIBRARY_PATH PATH=/usr/local/pgsql/bin:$PATH export PATH MANPATH=/usr/local/pgsql/man:$MANPATH export MANPATH All my library files are in /usr/local/pgsql/lib All my tsearch2,ltree files are in /usr/local/src/postgresql-7.4.23/contrib Any help would be appreciated Thanks!!! -- View this message in context: http://postgresql.1045698.n5.nabble.com/Importing-the-dump-file-in-postgresql-7-4-23-tp4578769p4581840.html Sent from the PostgreSQL - admin mailing list archive at Nabble.com. -- Sent via pgsql-admin mailing list (pgsql-admin@xxxxxxxxxxxxxx) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-admin
