Here's a quote from sql.el:

;; sql-interactive-mode is used to interact with a SQL interpreter
;; process in a SQLi buffer (usually called `*SQL*').  The SQLi buffer
;; is created by calling a SQL interpreter-specific entry function or
;; sql-product-interactive.  Do *not* call sql-interactive-mode by
;; itself.

That's what I wrote about previously.  If there are some other ways of
entering interactive sql mode, then I'm not aware of them, sorry.

First entry point, sql-product-interactive, calls specific comint
function, say sql-comint-postgres.  These product-specific functions
call sql-comint.

Second entry point(s), sql-postgres and the like, just call
sql-product-interactive.

So it all boils down to sql-comint in the end.

Sorry if I'm wrong somewhere.

Yes, thanks.
