call psql like this to set a variable named your_variable_name to my_table:
psql -v your_variable_name=my_table
to expand the variable your_variable_name to its value (my_table in this case)
in the sql script, precede its name with a colon, like so:
select * from :your_variable_name;
which will expand to:
select * from my_table;
the psql manpage has more info on all this.
Regards,
Daniel
