pgsql: Document that the regexp split functions ignore zero-length - Mailing list pgsql-committers

Log Message:
-----------
Document that the regexp split functions ignore zero-length matches in
certain corner cases.  Per discussion, the code does what we want, but
it really needs to be documented that these functions act differently
from regexp_matches.
