Description: ------------ The alterTable() function can only change a column's type if an implicit cast function is defined for the particular datatypes. If this is not the case (like for converting a 'text' column to 'integer'), PostgreSQL will return an error: ERROR: column "foo" cannot be cast to type "pg_catalog.int4" The attached patch adds an explicit cast to the ALTER TABLE command, allowing such conversions if an explicit cast function is defined. This is quite safe because it will still fail if a particular value can not be cast (for example, the string '42' can be converted to integer, but 'abc' can not).

This bug has been fixed in CVS. If this was a documentation problem, the fix will appear on by the end of next Sunday (CET). If this was a problem with the website, the change should be live shortly. Otherwise, the fix will appear in the package's next release. Thank you for the report and for helping us make PEAR better.
