BST Time Zone Discrepancy

["Igal @ Lucee.org" <igal@xxxxxxxxx>]

I've been having some issues with using BST as a timezone, so I checked the Postgres catalogs and found a discrepancy. 

I expected it to be British Summer Time, which is a Daylight Saving Time in England and has a 1-hour UTC offset.

In pg_timezone_abbrevs I see a 1-hr offset and is_dst set to true as I expected:

intranet=> SELECT * FROM pg_timezone_abbrevs WHERE abbrev='BST';
 abbrev | utc_offset | is_dst
--------+------------+--------
 BST    | 01:00:00   | t
(1 row)

But in pg_timezone_names I get an 11-hr offset with a completely different time zone.

intranet=> SELECT * FROM pg_timezone_names WHERE abbrev='BST';
            name            | abbrev | utc_offset | is_dst
----------------------------+--------+------------+--------
 Pacific/Bougainville       | BST    | 11:00:00   | f
 posix/Pacific/Bougainville | BST    | 11:00:00   | f
(2 rows)

Surely, they can not both be right, so I'm thinking that this is a bug?

Thank you,
