[Bug] create index using rum coredump on rumDatumWrite

[huey97]

Database Version: PostgreSQL 14.12 RUM extension version: rum 1.3 VECTOR extension: vector 0.6.2 Operating System: RHEL 8

The structure of the tables in the database is as follows: create extension rum; create extension vector; CREATE TABLE test_table ( a bigint, b character varying(32), c character varying(32), d character varying(32), e smallint, f character varying(64), g timestamp, h text[], i integer, j text, k public.vector(1536), l text, m tsvector, n smallint, p timestamp, q timestamp );

For security reasons, the data in the table cannot be provided directly. I found that when I inserted 40,000 or so rows into the table, the create index behaved differently as the amount of data changed.

CREATE INDEX idx ON public.test_table USING rum (h, m rum_tsvector_addon_ops) WITH (ATTACH='h', TO='m') WHERE id < 20000; will failed with "cannot store a toast pointer inside a range" in rumdatapage.c:115。

CREATE INDEX idx ON public.test_table USING rum (h, m rum_tsvector_addon_ops) WITH (ATTACH='h', TO='m') WHERE id < 40000 will coredump at "elog(ERROR, "cannot store a toast pointer inside a range");" in rumdatapage.c:115. The reason for coredump via ERROR here is that createPostingTree is in START_CRIT_SECTION() of ruminsert.c:67; The coredump is generated in subsequent errors.

The coredump stack is as follows： SQL: CREATE INDEX idx ON public.test_table USING rum (h, m rum_tsvector_addon_ops) WITH (ATTACH='h', TO='m');
