Description
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');
