I use PostgeSQL less than year. Before I worked with MS SQL Server 2000, MySQL 3&4, Oracle8i and Interbase. Also, I studied standards SQL:1999 and SQL:2003. So, after switching to PostgreSQL I've encountered with several things that seem strange to me. Of course, several of them are simply not implemented yet and are in the list of unsopported features: http://www.postgresql.org/docs/8.0/interactive/unsupported-features-sql-standard.html. But some seem to be 'old diseases'. Here is my list of the issues: http://chernowiki.ru/Dev/PostgreSQLComparedWithSQL2003AndOracleSQLServerDB2Etc Perhaps I'm wrong with some issues - any comments are welcome. On 08/10/05, Jim C.
