Build Identifier:

Would it be possible to handle rel_select.c:4473 more gracefully?

Reproducible: Always

Steps to Reproduce:

CREATE TABLE "sys"."kv6_import" (
"messagetype" VARCHAR(10) NOT NULL,
"operatingday" DATE NOT NULL,
"dataownercode" VARCHAR(10) NOT NULL,
"lineplanningnumber" VARCHAR(10),
"journeynumber" INTEGER NOT NULL,
"reinforcementnumber" INTEGER NOT NULL,
"userstopcode" VARCHAR(10),
"passagesequencenumber" INTEGER,
"distancesincelastuserstop" INTEGER,
"punctuality" INTEGER,
"rd_x" VARCHAR(11),
"rd_y" VARCHAR(11),
"blockcode" INTEGER,
"vehiclenumber" INTEGER,
"wheelchairaccessible" VARCHAR(5),
"source" VARCHAR(10) NOT NULL,
"numberofcoaches" INTEGER

select *, min(vehicle) over (partition by dataownercode, lineplanningnumber, journeynumber) from kv6_import where messagetype = 'ONROUTE' limit 10;

Actual Results:

Connection terminated

Expected Results:

I was if this query should give an equivalent result:

select * from kv6_import join (select min(vehicle) as vehicle, dataownercode, lineplanningnumber, journeynumber from "sys"."kv6_import" where messagetype = 'ONROUTE' group by dataownercode, lineplanningnumber, journeynumber) as groupby using (vehicle, dataownercode, lineplanningnumber, journeynumber) limit 10;

the implementations for windowed aggreation functions is misisng. The crash is coming from a assert(0), which is just there to inform us of this missing feature.
