Column names - time

In moving from 7.1.3 to 7.2devel (for bug fixes) we've encountered a
problem with a, previously valid, column name: time. In 7.1.3 the
following worked:
 CREATE TABLE test(time INTEGER);

while in 7.2devel it results in a parse error:
 ERROR:  parser: parse error at or near "time"

Looking at the source I see this is a result of 'time' being added to
ColLabel in backend/parser/gram.y earlier this month.

This effects interface code and database migration using pg_dump.

Obviously a new column name will have to be used, however is there a
definitive list of keywords to avoid so such an occurance wouldn't
happen in a production system? Currently these include:
 abort all analyse analyze and any asc between binary bit both case cast char character check cluster coalesce collate
columnconstraint copy cross current_date current_time current_timestamp current_user dec decimal default deferrable
descdistinct do else end except exists explain extract false float for foreign freeze from full global group having
