pgsql 7.1.2 server hanging...

I am trying out postgresql 7.1.2.  I'm experiencing a hung server on
linux 2.4.2-2 when I run a sql script that drops & reloads many PL/pgSQL
functions and triggers, as well as hanging during VACUUM ANALYZE.  That
last thing I see in the logs is as follows:

2001-06-25 17:35:19 [3718]   DEBUG:  query: DROP TRIGGER
person_insert_trigger ON person;
2001-06-25 17:35:19 [3718]   DEBUG:  ProcessUtility: DROP TRIGGER
person_insert_trigger ON person;
2001-06-25 17:35:38 [3719]   DEBUG:  MoveOfflineLogs: remove
0000000000000008

During VACUUM ANALYZE the last log messages are:

2001-06-25 18:14:15 [3866]   DEBUG:  --Relation pg_toast_16600--
2001-06-25 18:14:15 [3866]   DEBUG:  Pages 4: Changed 2, reaped 0, Empty

Tuples 14. CPU 0.00s/0.00u sec.

Any clues or helpful diagnostic questions?
