These algorithms introduce a random behavior in the ordering + of query results when the query contains multiple qualifiers or multiple + tables (giving the optimizer a choice on order of evaluation). Several + regression tests have been modified to explicitly order the results, and + hence are insensitive to optimizer choices. A few regression tests are + for data types which are inherently unordered (e.g. points and time + intervals) and tests involving those types are explicitly bracketed with + <Command>set geqo to 'off'</Command> and <Command>reset geqo</Command>. +</Para> + +<Para> + The interpretation of array specifiers (the curly braces around atomic + values) appears to have changed sometime after the original regression + tests were generated.
