=head1 DESCRIPTION
-See L<DBIx::Class::Schema::Loader::Base> for available options.
+See L<DBIx::Class::Schema::Loader> and L<DBIx::Class::Schema::Loader::Base>.
+
+=head1 COLUMN NAME CASE ISSUES
+
+By default column names from unquoted DDL will be generated in lowercase, for
+consistency with other backends.
+
+Set the L<preserve_case|DBIx::Class::Schema::Loader::Base/preserve_case> option
+to true if you would like to have column names in the internal case, which is
+uppercase for DDL that uses unquoted identifiers.
+
+Do not use quoting (the L<quote_char|DBIx::Class::Storage::DBI/quote_char>
+option in L<connect_info|DBIx::Class::Storage::DBI/connect_info> when in the
+default C<< preserve_case => 0 >> mode.
+
+Be careful to also not use any SQL reserved words in your DDL.
+
+This will generate lowercase column names (as opposed to the actual uppercase
+names) in your Result classes that will only work with quoting off.
+
+Mixed-case table and column names will be ignored when this option is on and
+will not work with quoting turned off.
