Does anyone know of any issues around ARRAY UNNEST - Mailing list pgsql-sql
Hi there,
--
We're having segmentation faults on our postgres 9.1.1 db. It seems to happen when we use ARRAY unnesting eg:
UPDATE activity SET activity_recency_timestamp = CURRENT_TIMESTAMP WHERE venue_id IN (SELECT venue_id FROM UNNEST(v_venue_id_list) venue_id);
We are working on a getting a core dump but I was just wondering if there are any known issues around this construct - especially the aliasing?
Alternatively could there be an issue trying to write or access tmp files?
FYI:
v_venue_id_list is an array passed in to the procedure containing 100,000 INTEGER elements
? IS THIS TOO MANY ELEMENTS TO PASS?
table activity has around 3,000,000 rows
CREATE TABLE activity
(
activity_id serial NOT NULL,
activity_type_key integer NOT NULL,
media_type_key integer NOT NULL,
activity_source_key integer NOT NULL,
venue_id integer NOT NULL,
poster_id integer NOT NULL,
event_id integer,
activity_source_id_value text NOT NULL,
uri text,
media_uri text,
activity_comment text,
posted_dttm timestamp with time zone,
photo_format_code character varying(10),
video_format_code character varying(10),
public_yn character varying(1),
content_reported_yn character varying(1),
last_scored_tstamp timestamp with time zone,
record_expiry_tstamp timestamp with time zone,
record_created_tstamp timestamp with time zone DEFAULT now(),
record_last_updated_tstamp timestamp with time zone DEFAULT now(),
initial_broadcast_to_text text,
image_id integer,
large_media_uri text,
CONSTRAINT activity_pkey PRIMARY KEY (activity_id ),
CONSTRAINT activity_activity_source_key_activity_source_id_value_key UNIQUE (activity_source_key , activity_source_id_value )
);
CREATE INDEX activity_poster_ie
ON activity (poster_id );
CREATE INDEX activity_venue_ie
ON activity (venue_id );
