[GENERAL] aliases for sequences and other DB objects?

[Agoston Postgres]

Hi!

Is it possible in Postgres to specify aliases for various DB objects, such as 
tables, views, sequences, etc.? (For now I would like to create them for 
sequences.)

What I mean is something like in Oracle, such as

create alias my_sequence_alias for my_sequence;
select nextval('my_sequence_alias');


Thanks!
