Hello Tom,
there is not much to provide. It is just the update statement mentioned in the
text above. the table structure i a parent table with titles, authors and
other small infos. two subtables with pictures and text fields are referenced
to the parent table. the error occurs on the subtable with the text datatype.
newsdb2=# \d dpa_text
Table "public.dpa_text"
Column | Type | Modifiers
------------+--------------+---------------------------------------------------------
textid | integer | not null default
nextval('"dpa_text_textid_seq"'::text)
id | integer | not null
volltext | text | not null
update_tag | character(1) | default 't'
titleidx | txtidx |
Indexes: dpa_text_pkey primary key btree (textid),
d_te_id_idx btree (id),
dpa_text_oid_id_idx btree (oid),
dpa_txt_t_idx gist (titleidx)
Triggers: RI_ConstraintTrigger_9882551
I am running this on the tables to build the tsearch index:
bash-2.03$ less make_dpa_index.sql
update dpa set titleidx=txt2txtidx(dachzeile);
update dpa set titleidx=txt2txtidx(ueberschrift);
update dpa set titleidx=txt2txtidx(zwischentitel);
update dpa set titleidx=txt2txtidx(vorspann);
update dpa set titleidx=txt2txtidx(kurztext);
update dpa_text set titleidx=txt2txtidx(volltext);
this produces the output:
bash-2.03$ time psql newsdb2 <make_dpa_index.sql
UPDATE 110992
UPDATE 110992
UPDATE 110992
UPDATE 110992
