How else to make a serial SQL definition - Mailing list pgsql-novice

I couldn't figure out what mailing list would be the right place for this question

I need to know if there is a SQL table creation method that would work for both
PostgreSQL and MySQL to create a incremental field like 'id serial'

My program needs to access the sequence value after a record is added to create a
link to it from another table

I have it working in Perl for PostgreSQL but would like for it also to work under MySQL
