I strongly recommend closing this conversation now. I've made all the
points I can make as clearly as I can make them, and I'm not having any

[..] The default implementation of quoted_identifier will work with
DBD::Informix if the program has DELIMIDENT set

I don't see how quote_identifier helps a user of DBI write more portable

Suppose I'm writing a cross DBMS system that needs to interact with various
(unkown at compile time) database objects. Suppose I want to display a list
of objects in the database, perhaps
Good points. Thanks.
I guess the problems we're trying to address are (at least):
a) How should an app correctly quote an identifier if it wants to
(for whatever reason).
b) How to ensure that the results of $dbh-tables, $dbh-table_info,
$dbh-column_info etc. are usable in SQL statements

If a database do not support quoting, wouldn't be up to the DBD driver to
complain loudly when someone tries to quote something, and otherwise just
be a no-op?
No need to complain. quote_identifier would just return the unquoted

With Synase ASA you can use SELECT CONNECTION_PROPERTY ('QUOTED_IDENTIFIER')

No. The SQL should have been constructed by the application calling
quote_identifier() on any identifiers it contains.
The issue is how your DBD's quote_identifier implementation knows
whether it should quote or

FYI, here's what I'm playing with at the moment:
sub quote_identifier {
my $dbh = shift;
my @id = grep { defined } @_; # ignore null elements (ie catalog, schema)
