RAISE NOTICE has been mentioned.

Apart from the possibility to write file I/O functions in Perl,
there are some functions that are already included in PostgreSQL:
pg_read_file and pg_stat_file.
The contrib module "adminpack" provides pg_file_write,
pg_file_rename, pg_file_unlink.

Together these are enough for simple file system access,
although they don't provide as much as UTL_FILE.
