However, there seems to be an inconsistency, in that:

sql-connection-alist says "CONNECTION is a symbol identifying the connection"

whereas sql-connect (above) assumes it to be a string.
AFAICS, sql-save-connection also saves strings rather than symbols for NAME.

So maybe it is a doc bug?


On a semi-related note:

emacs -Q -l sql
M-x sql-connect
  -> "Wrong number of arguments" error
