pgsql: Fix incorrect results for numeric data passed through an ECPGSQ - Mailing list pgsql-committers

Fix incorrect results for numeric data passed through an ECPG SQLDA.

Numeric values with leading zeroes were incorrectly copied into a
SQLDA (SQL Descriptor Area), leading to wrong results in ECPG programs.

Report and patch by Daisuke Higuchi.  Back-patch to all supported
versions.
