some thinking. This is other functionality and can be nice in psql too
- but it can be more automatic - only

\ef"E" without others parameters - like show line on last error -
without writing function name, without writing line number - both
information can be in error buffer. But you have to design universal
mechanism for editor call with line number parameter (isn't big
problem probably). And it's slower - you have to start second
application.

What about some hypotetical statement Show Function?

\sf name  -- show function
\sf name, line  -- show function from line
