I am on development version. This does not happen always.

I do:

- M-x sql-postgres and enter

- then at the exact moment when I click SQL menu, I get this error:

Debugger entered--Lisp error: (error "‘'postgres’ is not a known product; use 
‘sql-add-product’ to add it first.")
  signal(error ("‘'postgres’ is not a known product; use ‘sql-add-product’ to 
add it first."))
