Description

For the case when cast with decimal literal is used and literal has less precision than specified in the casting type:

SELECT cast('999.99' as decimal(9, 4)) decimal_9_4

the precision in column metadata is incorrect: 7, but should be 9.

Test which has the similar check PreparedStatementTest.testQueryMetadataInPreparedStatement is failed when it is ran separately.
