Hi, There's already a couple of SQL function dealing with XLogRecPtrs and the logical replication work will add a couple of more. Currently each of those funtions taking/returning an LSN does sprintf/scanf to print/parse the strings. Which both is awkward and potentially noticeable performancewise.
It seems relatively simple to add a proper type, with implicit casts from text, instead?
