Sorry (was deep in thoughs while coding...). A bit more detailed:

I am using libpq, the C language pg library. There is a useful function
to return the last error message as human readable text: PQerrorMessage.

While the returned text message is static memory which is good (you
simply print it and don't have to free the memory) there is a trailing
new line character at each text message like this:
<message text><newline><0-byte-terminator>

I find this newline a lot uncommon--since it is easy to add manually if
you really want it, and, however, it is not so easy to get rid of it.

Getting rid of it means: Copying the whole string without the newline,
pass it to the user, who has to free the copied memory after printing
it...

I wanted to know if there is a switch or similar somewhere to get the
messages without newline character.

Thank You
