We are working in a rather complex environment, where COBOL/SQL on a
legacy
mainframe has its SQL portions sent via a high speed link to a Unix box.
The SQL is translated to a C/SQL environment in the process and the
Postgres
ECPG preprocessor is used on the Unix side for interfacing with Postgres.
We are already doing a translation from trailing blank Cobol strings
to C null terminated strings in this process for the connection host
variables.
The reasons for requesting a Postgres option to strip trailing blanks in
this case are:
1) we are not the only project to run into the problem of Postgres being
oriented towards C strings
2) other RDBMS systems use the expected trimming of Cobol trailing blanks
3) when porting Oracle Cobol applications to Postgres, this option would
be helpful
4) it might be better to strip the trailing blanks in the application if
only one such application were involved,
but when there are several such applications, centralizing the
behavior in a Postgres option is preferrable

Which preprocessor are you using? I wonder if such a logic should better
be implemented in the Cobol-C transition instead.
