Execute several .sql files in a single transaction using PostgreSQL and bash

You can also use the -1 or --single-transaction option to execute all your scripts in a transaction:

cat file*.sql | psql -1

Either use a sub-shell:

#!/bin/sh
 (echo "BEGIN;"; cat file1.sql; cat file2.sql; echo "COMMIT;") \
 | psql -U the_user the_database

#eof

or use a here-document:

#!/bin/sh
psql -U the_user the_database <<OMG
BEGIN;

\i file1.sql

\i file2.sql

COMMIT;
OMG

#eof

NOTE: in HERE-documents there will be no globbing, so file*sql will not be expanded. Shell-variables will be expanded, even within quotes.
