PEAR DB - some suggested improvements

Hello, While reviewing PEAR DB for a book I'm writing, I found a few issues that can be improved in PEAR DB. 1. PEAR DB's error handling does not capture the error message, only the error number. I would suggest including the error message, because it often contains info specific to the error, such as in what column the SQL syntax error occurred. 2. The oci8 driver attempts to return the numRows() by changing the select statement to a select count(*). This will only work in a single-user or read-only environment. Better to accept defeat and just return -1. 3. The isManip() function will not work properly with some databases that allow stored procedures to return recordsets. I would suggest deprecating it.
