Couldn't we use a fast code path (what we have now) for the case when the delimiter is a single byte? That would allow for multi-character delimiters without penalizing those that don't use them. As for use case, I worked on migrating some stuff out of a MySQL database a while ago, and having arbitrary string delimiters would have made life easier. -- Jim Nasby jim@nasby.net EnterpriseDB http://enterprisedb.com 512.569.9461 (cell)
