That sounds like the right first steps to me. Reviewing this discussion, it was my thought to create a new node, ala seqscan, which implemented analyze's algorithm for scanning the table. The eventual idea being that analyze would actually use it in the future. There was mention up-thread about just calling the analyze code. Personally, I'd rather we make analyze more SQL like (once we have this functionality implemented) than make things which are supposed to be SQL call out into analyze bits. Thoughts? Other opinions? Thanks, Stephen
