See the "name" data type.

As for enlarging it; I'll bet yes but you'll have to compile from source
to do this.

Someone on the hackers list can better explain :-)

See:

4.1.1. Identifiers and Key Words


Our table names are and fully descriptive, and our code depends on a
predictable sequence naming convention of the PG default
<table>_<column>_seq.

Yes, I know that its not a great idea to depend on consistent naming
conventions!
