Thanks for the updated patch.
Now when I run the test program (version with better error reporting
attached), it runs fine until I open a psql session and issue:
reindex table foo;
Then it immediately falls over with some rows no longer being findable
through the index.
-- use index
select count(*) from foo where text_array = md5(4611::text);
0
-- use seq scan
select count(*) from foo where text_array||'' = md5(4611::text);
1
Where the number '4611' was taken from the error message of the test
program.
