You would probably be better off writing your scripts in a
system language such as Python or Perl. Here is an excerpt from
a basic Python backup program I wrote (uses pg_dump &
postgresql-python) that does just that.
#!/usr/bin/python
import os, time
from pg import DB
# Backup database with the current date attached
def pg_backup():
now = time.localtime(time.time())
today = time.strftime("%m-%d-%Y", now)
os.system("pg_dump test > test-%s.sql" % today)
print "Backup completed"
# Run vacuum on database
def pg_clean():
cxn = DB('test')
cxn.query("VACUUME VERBOSE ANALYZE")
print "Database optimized & space recovered"
### This is the main program ###
if __name__ == "__main__":
pg_backup()
pg_clean()
