"Function unaccent(text) does not exist" in update trigger
I've created a trigger for table
x1to update a column
ywith the expression
to_tsvector(unaccent(x1.col1 || ' ' || x2.col1)). This trigger function throws:
function unaccent(text) does not exist
Why would this function not exist when a trigger is called, but exist when executed manually? I'm using Supabase to manage this database.
unaccent()is typically the one installed by the additional module https://www.postgresql.org/docs/current/unaccent.html . See:
Additional modules can be installed to any schema. (I like to use a dedicated schema.) See:
If so, then the schema must be added to the https://stackoverflow.com/a/9067777/939860 to allow function calls without schema-qualification like you demonstrate.
The obvious explanation for your observation would be that you call the function in one session with an appropriate
search_path, and execute the trigger in another session with a different
To diagnose, add this line to your PL/pgSQL trigger function just before the command calling
unaccent()temporarily (and make sure notices are logged or reported to the client, depending on where you look):
RAISE NOTICE 'Current search_path: %', current_setting('search_path');
The simple & safe fix is to schema-qualify the function name. Like:
But investigate whether schemas and the
search_pathare handled properly across your DB cluster ...
