I just restored database to Firebird 3. It seems, that FB3 is faster,
but it might be, because it is fresh restore. 
In 2.5:
UDF: 25 sec
selectable SP (PSQL): 50 sec

In 30:
UDF: 20 sec
selectable SP (PSQL): 30 sec
PSQL function: 30 sec

It is basically big query, where function is used for checking every
record for 1263597 records.
