Postgresql: backup and restore functions

BU-restore functions in postgresql

# First, make a dump of the database without data (-s)
$ pg_dump -h localhost -U username -Fc -s -f db_dump dbName

# Create a list of the functions
$ pg_restore -l db_dump | grep FUNCTION > function_list

# Restore the functions in an other database
$ pg_restore -h localhost -U username -d other-dbName -L function_list db_dump

Hi denitram, Thank you for saving my time.
It's Better if you can do it for tables on database to.

Thank You!
