 Environment: Ubuntu 22.04 lts, postgres 15 installed via postgres.org repository

I am attempting to use the system information functions here: https://www.postgresql.org/docs/15/functions-info.html

I’m logged on as the postgres superuser on the host

Trying any of the functions gives me a syntax error

postgres=# pg_database_size(avi);

ERROR:  syntax error at or near "pg_database_size"

LINE 1: pg_database_size(avi);

 

Do I have to add anything to the search_path?

postgres=# show search_path;

   search_path   

-----------------

 "$user", public

(1 row)

And single quote name. 'avi'
