ecpg: Restore detection of unsupported COPY FROM STDIN.
The ecpg command includes code to warn about unsupported COPY FROM STDIN
statements in input files. However, since commit 3d009e45bd
,
this functionality has been broken due to a bug introduced in that commit,
causing ecpg to fail to detect the statement.
This commit resolves the issue, restoring ecpg's ability to detect
COPY FROM STDIN and issue a warning as intended.
Back-patch to all supported versions.
