PostgreSQL function for last inserted ID

Question

In PostgreSQL, how do I get the last id inserted into a table?

In MS SQL there is SCOPE_IDENTITY().

Please do not advise me to use something like this:

Answer 1

SELECT CURRVAL(pg_get_serial_sequence('my_tbl_name','id_col_name'))

You need to supply the table name and column name of course.
