interval input "invalid" was specified together with other fields. Spotted by Neil Conway with the help of a clang warning. Although this has been wrong since the interval code was written more than 10 years ago, it doesn't affect anything beyond which error message you get for a wrong input, so not worth back-patching very far.
$PostgreSQL: pgsql/src/interfaces/ecpg/README.dynSQL,v 1.3 2008/03/21 13:23:28 momjian Exp $ descriptor statements have the following shortcomings - input descriptors (USING DESCRIPTOR <name>) are not supported Reason: to fully support dynamic SQL the frontend/backend communication should change to recognize input parameters. Since this is not likely to happen in the near future and you can cover the same functionality with the existing infrastructure (using s[n]printf), I'll leave the work to someone else.
