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
