psql execute stored function and store the result in the variable

I need to execute sql function and store the result

#!/bin/bash  

RESULT=`psql -A -t postgresql://user:password@localhost:5432/db -c "select main.return_anything();" db`

echo $RESULT

And expect the result to contain 1.

But I get the result

psql: warning: extra command-line argument "select main.return_anything();" ignored

psql: warning: extra command-line argument "db" ignored

And it is just waiting for something and not produce any result. What is the problem?

From psql manual:

psql [option...] [dbname [username]]

So first options, then optionally dbname and then optionally username.

Try this:

RESULT=$(psql -A -t -c "select main.return_anything();" postgresql://user:password@localhost:5432/db db)

Side note: backticks ` are deprecated. Use $(...) which look cleaner and allow for nesting.
