You can use a code from Postgres documentation mentioned by michel-sim. Other possibility is Orafce extension - https://github.com/orafce/orafce or http://postgres.cz/wiki/Oracle_functionality_%28en%29 that is available for RedHat or Debian as binary package too.

I'm try to convert my Oracle function which contains SUBSTR()
to PostgreSQL. Is there an equivalent function in PSQL? Thanks.
I manage to find a Oracle Instr() conversion to PostgreSQL.

There's substring
, but you'd have to modify the invocations -- instead of substr(x, i, j)
you need substring(x from i to j)
