--- Comment #7 from Jorge Teixeira <[email protected]> ---
The current behavior of showing the current number of loaded records is very
misleading, but I understand that requiring to load all records into memory by
default would be even worse.

Some (most?) SQL engines have the ability to report internal/management stats
which include **approximate** row counts with little overhead. I don't know if
this is available in ODBC/etc. in a standardized way.

A COUNT(*) query would provide the exact number, at significant overhead for
large tables, and should work with all backends.

Perhaps this RFE would be more feasible if there was first a form property
"rowsTotalCountPreview" with possible values "Currently loaded records
(default)", "Exact total count (very slow)", with availability "Approximate
total count (fast)" depending on the type of backend/etc..
