Agreed. I have changed the code to use NAMEDATALEN. > ==== 2. extern PGDLLIMPORT ==== > pg_upgrade has own definitions of > extern PGDLLIMPORT Oid binary_upgrade_next_xxx > in pg_upgrade_sysoids.c. But those variables are not declared as > PGDLLIMPORT in the core. Can we access unexported variables here? The issue here is that you use PGDLLIMPORT where you are importing the variable, not where it is defined. For example, look at 'seq_page_cost'. You can see PGDLLIMPORT used where it is imported with 'extern', but not where is it defined. > ==== 3. pathSeparator ==== > Path separator for Windows is not only \ but also /.

I have modified the code to use only "/" and check for "/" and "\". It is used only for checking the last byte so I didn't think it would affect a multi-byte sequence. I am actually unclear on that issue though. Can you review the new code to see if it is OK. > ==== 4.
