Why not use unique_ptr<> ?

[01e9]

This is just a question, you can close this issue right away.

The below code is like this for a reason or just a habit?

libpqxx/src/connection_base.cxx

Lines 1041 to 1054 in a70fb65

	char *const buf = new char[2*maxlen+1];
	try
	{
	int err = 0;
	PQescapeStringConn(m_conn, buf, str, maxlen, &err);
	if (err) throw argument_error(err_msg());
	escaped = std::string(buf);
	}
	catch (const std::exception &)
	{
	delete [] buf;
	throw;
	}
	delete [] buf;

You're right — that looks like a case for std::vector<char>. All I can say is I probably wrote this a long, long time ago.

Fixing it now!
