I found another problem in the latest patch. When I issued the following SQLs,
I got the assertion failure.
CREATE EXTENSION pg_trgm;
CREATE TABLE hoge (col1 text);
CREATE INDEX hogeidx ON hoge USING gin (col1 gin_trgm_ops) WITH
(fastupdate = off);
INSERT INTO hoge SELECT random()::text FROM generate_series(1,100);
REINDEX TABLE CONCURRENTLY hoge;
The error message that I got is:
TRAP: FailedAssertion("!(((array)->elemtype) == 25)", File:
"reloptions.c", Line: 874)
LOG: server process (PID 45353) was terminated by signal 6: Abort trap
DETAIL: Failed process was running: REINDEX TABLE CONCURRENTLY hoge;
ISTM that the patch doesn't handle the gin option "fastupdate = off" correctly.
Anyway, I think you should test whether REINDEX CONCURRENTLY goes well
with every type of indexes, before posting the next patch. Otherwise,
I might find
another problem ;P
