It really depends on how you want to use the variables in the script.
psql has a '-v' option which you can use to set variables that can be
used with the ':varname' syntax inside of the script, for example:
psql -v table=abc -f script.sql
Inside of script.sql you can then have ':table', like so:
select * from :table;
and that ':table' will be replaced by 'abc' when psql is run with the
'-v table=abc' parameter.
Hope that helps!
Thanks!
Stephen
