Thanks, builds fine now.
But I found that the server crashes on certain forms of SQL when
postgresql.conf has a 'shared_preload_libraries' that contains module
'pg_stat_statements' (my value was:
'pg_stat_statements,auth_delay,auto_explain,passwordcheck'). Only
pg_stat_statements seems to cause the problem.
The offending SQL (I took it from the jsonb_sqljson.sql test file):
testdb=# SELECT JSON_EXISTS(jsonb '{"a": 1, "b": 2}', '$.* ? (@ > $x &&
@ < $y)' PASSING 0 AS x, 2 AS y);
server closed the connection unexpectedly
This probably means the server terminated abnormally
before or while processing the request.
The connection to the server was lost. Attempting reset: Failed.
Time: 2.551 ms
!?>
(Of course, that SQL running during regression testing has no problems
as there is then no pg_stat_statements.)
The statement sometimes succeeds but never very often.
The same crash was there before but I only now saw the connection with
the 'shared_preload_libraries/pg_stat_statements'.
I seem to remember some things changed in pg_stat_statements but I
didn't follow and don't know who to CC for it.
Thanks,
