It could be a pgAdmin III presentation fault. I'm using PostgreSQL 8.0.0 on Windows 2k and I've got the same problem but only when inquiring via pgAdmin, using psql from command line all goes ok. I think that the resulting string are correct, that's why the function "position(\'.\' in userName);" doesn't find the dot.

I'm skeptical: there is nothing special about 256 characters as far as the varchar implementation is concerned, nor is the string ' (.' of any significance. Running your function (albeit on Linux) yields: neilc=# select testconverttousername(); testconverttousername ------------------------------------------------------------------------ ------------------------------------------------------------------------ ------------------------------------------------------------------------ -------------------------------------------- 123456781234567812345678123456781234567812345678123456781234567812345678 123456781234567812345678123456781234567812345678123456781234567812345678 123456781234567812345678123456781234567812345678123456781234567812345678 123456781234567812345678123456781234567888 (1 row) i.e. what one would expect. -Neil ---------------------------(end of broadcast)--------------------------- TIP 5: Have you checked our extensive FAQ? http://www.postgresql.org/docs/faq ---------------------------(end of broadcast)--------------------------- TIP 7: don't forget to increase your free space map settings
