I set breakpoint at src/backend/optimizer/util/clauses.c:188 and do some trace,
may be this can help:
Breakpoint 1, get_leftop (clause=0x7fe1f1d5af30)
(gdb) print *expr
$1 = {xpr = {type = T_OpExpr}, opno = 96, opfuncid = 65, opresulttype = 16,
opretset = 0 '\000', opcollid = 0,
inputcollid = 0, args = 0x7fe1f1d5cb98, location = 0}
Breakpoint 1, get_leftop (clause=0x7fe1f1d5c4b0)
(gdb) print *expr
$2 = {xpr = {type = T_OpExpr}, opno = 96, opfuncid = 65, opresulttype = 16,
opretset = 0 '\000', opcollid = 0,
inputcollid = 0, args = 0x7fe1f1d5cc40, location = 0}
Breakpoint 1, get_leftop (clause=0x7fe1f1d5c0b8)
(gdb) print *expr
$3 = {xpr = {type = T_ScalarArrayOpExpr}, opno = 96, opfuncid = 65,
opresulttype = 1, opretset = 0 '\000', opcollid = 0,
inputcollid = 4057317752, args = 0x1b, location = -237649736}
