Well, if you call a pl function, it is going to show you the current SPI
function running rather than the user query. Because the comment next
to the function says:
* Expose the current query to the user (useful in stored procedures)
I assume the portal string is better for stored procedures then
debug_query_string for current_query().
As I remember, there was lots of objection to adding current_query()
because it seemed useless, but the stored procedure logic won us over,
and I assume the portal string is a better representation for that
usage. In fact, because the application knows the query string, you
could argue that anything that has more information than the client
query string is preferable.
But of course I might be wrong. ;-)
