Build Identifier:

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

Reproducible: Always

Steps to Reproduce:

CREATE TABLE "sys"."kv6_import" (
"receive" TIMESTAMP NOT NULL,
"message" TIMESTAMP NOT NULL,
"vehicle" TIMESTAMP NOT NULL,
"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.

The window functions will be available in the next feature release.
