Hi,
sqlsmith triggered the following assertion in master (c188204).
TRAP: FailedAssertion("!(!bms_overlap(joinrelids, sjinfo->min_lefthand))", File: "joinrels.c", Line: 500)
As usual, the query is against the regression database. It is rather
unwieldy… I wonder if I should stop working on new grammar rules and
instead work on some post-processing that prunes the AST as much as
possible while maintaining the failure mode.
regards,
andreas
