Setting global parameter in Postgres 8.3

Hi All,

Is there any way we can set the global parameter in Postgres 8.3?

As I have a sql script which need to accept some parameter at run time. For example I have sql script for creating tablespaces called “create_tablespace.sql”

Inside the sql script I have the following statements

CREATE TABLESPACE bank_index_tbsp OWNER bank LOCATION '$drive/data/bank/index_tbsp';

CREATE TABLESPACE bank_master_tbsp OWNER bank LOCATION ‘$drive/data/bank/master_tbsp';

CREATE TABLESPACE bank_static_tbsp OWNER bank LOCATION ‘$drive /data/bank/static_tbsp';
