When I use the nvl function, I receive the following error. Please advise.

dev_db=> SELECT nvl( sum(salary), 0 ) as b FROM db.employee WHERE user = ‘testuser’;
ERROR: function nvl(numeric, integer) does not exist
LINE 1: SELECT nvl( sum(salary), 0 ) as b FROM db.employee

The coalesce functions in PostgreSQL are supported but not the NVL functions. Similar to Oracle, this method is used. Converting NVL and using Oracle’s coalesce operations are both possible with coalesce. The arguments must be of the same type or be capable of being automatically typed into the same type.

Solution : NVL function should be changed to COALESCE.
