I have never seen this problem before. It occurred while trying to import
a dump (done by 9.5 client of a 9.4 database) also.
Table definition:
-
CREATE TABLE source.annual
(
filename text,
gzipfile text,
id serial NOT NULL,
tsv tsvector,
ut character varying(19),
xml xml,
processed boolean,
CONSTRAINT annual_pkey PRIMARY KEY (id)
)
WITH (
OIDS=FALSE
);
CREATE INDEX xml_tsv_idx
ON source.annual
USING gin
(tsv);
CREATE TRIGGER tsvectorupdate_source_xml
BEFORE INSERT OR UPDATE
ON source.annual
FOR EACH ROW
EXECUTE PROCEDURE source.update_xml_tsv();
And the trigger function:
CREATE OR REPLACE FUNCTION source.update_xml_tsv()
RETURNS trigger AS
$BODY$
begin
new.tsv := to_tsvector('english', coalesce(new.xml,''));
return new;
end
$BODY$
LANGUAGE plpgsql VOLATILE
COST 100;
When I try to insert a value into this table, I get:
==================================
ERROR: function to_tsvector(unknown, xml) does not exist
LINE 1: SELECT to_tsvector('english', coalesce(new.xml))
^
HINT: No function matches the given name and argument types. You might
need to add explicit type casts.
QUERY: SELECT to_tsvector('english', coalesce(new.xml))
CONTEXT: PL/pgSQL function source.update_xml_tsv() line 5 at assignment
********** Error **********
ERROR: function to_tsvector(unknown, xml) does not exist
SQL state: 42883
Hint: No function matches the given name and argument types. You might need

=============================================
But I can do
select to_tsvector('English', 'This is a problem')
without a problem.
What is causing this?
