Bug: after vacuum analyze, I'm unable to do a simple select. Instead I'm
getting this error:
ERROR: datumGetSize: Invalid typLen 0
Many thanks to Teodor Sigaev for helping verify this bug. The following
test suite came from Teodor:
Reproduce bug:
initdb and start postmaster
%createdb foo
%psql foo < bug.sql
CREATE TABLE
INSERT 16996 1
INSERT 16997 1
CREATE TABLE
INSERT 17003 1
ts_name | ts_name
---------+---------
default | default
default | default
(2 rows)
VACUUM
ERROR: datumGetSize: Invalid typLen 0
bug.sql is very simple:
------------------------------------------------
CREATE TABLE pg_ts_cfgmap (
ts_name text
);
insert into pg_ts_cfgmap values ('default');
insert into pg_ts_cfgmap values ('default');
CREATE TABLE pg_ts_cfg (
ts_name text
);
insert into pg_ts_cfg values ('default');
select
*
from
pg_ts_cfgmap,
pg_ts_cfg
where
pg_ts_cfgmap.ts_name = pg_ts_cfg.ts_name;
vacuum analyze pg_ts_cfgmap;
select
*
from
pg_ts_cfgmap,
pg_ts_cfg
where
pg_ts_cfgmap.ts_name = pg_ts_cfg.ts_name;
