In community v16 I get: (gdb) p (NodeTag) 444 $1 = T_String You might have better luck identifying just where it's failing if you recompile nodeFuncs.c with -O0. The most obviously fishy thing I'm seeing in your code is > A_Expr *onConflictWhereExpr = makeSimpleA_Expr(AEXPR_OP, "<", (Node > *)conflictColumnRef, > (Node *)makeConst(INT8OID, -1, InvalidOid, sizeof(int64), > Int64GetDatum((int)myTimestamp), false, true), -1); An A_Expr is only valid in raw_parser output, but what you seem to be trying to construct is a post-parse-analysis tree. regards, tom lane
