I loved Firebird but now we have to have some cool things that Postgres has
and Firebird doesn´t.
Fiirebird has just 3 cool features that Postgres doesn´t: Computed by
columns, Position for fields and triggers and execute blocks, just that.
Replication, PITR, JSON and JSONB, XML, inherited tables, arrays, grouping
sets, User defined datatypes, SELECT without a FROM clause, Parallel
queries, Tuple comparison, Transactional DDL and a lot of other useful
things that Firebird doesn´t know what it is.
