File output functions in PL/pgSQL?

Hi,

Can one open, close and write to a file from a PL/pgSQL function?
I am porting an Oracle database to Postgres and the database contain
some functions that create text files to export certain data.

The functions used in Oracle is:
file_handle := UTL_FILE.FOPEN(...);
UTL_FILE.FCLOSE(file_handle);
UTL_FILE.PUT(file_handle, 'xxx');

I did not find anything in the mail archives or Google.

Any suggestions?

Thanks
