In my particular case the function was actually missing  The error message is the same  I am using the Postgresql plugin PostGIS and I had to reinstall that for whatever reason

Your function has a couple of smallint parameters  But in the call  you are using numeric literals that are presumed to be type integer   A string literal or string constant   123   is not typed immediately  It remains type  unknown  until assigned or cast explicitly   However  a numeric literal or numeric constant is typed immediately  Per documentation      A numeric constant that contains neither a decimal point nor an   exponent is initially presumed to be type integer if its value   fits in type integer  32 bits   otherwise it is presumed to be type   bigint if its value fits in type bigint  64 bits   otherwise it is   taken to be type numeric  Constants that contain decimal points and or   exponents are always initially presumed to be type numeric    More explanation and links in this related answer    PostgreSQL ERROR  function to tsvector character varying  unknown  does not exist   Solution  Add explicit casts for the smallint parameters or quote them   Demo  CREATE OR REPLACE FUNCTION f typetest smallint    RETURNS bool AS  SELECT TRUE  LANGUAGE sql   Incorrect call   SELECT   FROM f typetest 1     Correct calls   SELECT   FROM f typetest  1    SELECT   FROM f typetest smallint  1    SELECT   FROM f typetest 1  int2   SELECT   FROM f typetest  1   int2     db lt  fiddle here Old sqlfiddle

That error means that a function call is only matched by an existing function if all its arguments are of the same type and passed in same order  So if the next f   function  create function f   returns integer as         select 1     language sql    is called as  select f 1     It will error out with  ERROR   function f integer  does not exist LINE 1  select f 1                    HINT   No function matches the given name and argument types  You might need to add explicit type casts    because there is no f   function that takes an integer as argument   So you need to carefully compare what you are passing to the function to what it is expecting  That long list of table columns looks like bad design
