Refer to multiple .sql files

[bwragg]

I was wondering if its possible to refer to a .sql file from another .sql file. What I want to do is run a master script (ms.sql) in psql and for ms.sql to point to child .sql scripts. e.g c1.sql, c2.sql, c3.sql.

Can you do something like the following ms.sql:

insert ....
insert ....
update ....
load c1.sql
load c2.sql
insert ....
update ....

Thanks,

Benjamin
