Thanks. Pushed, and back-patched to 14, where min_dynamic_shared_memory arrived. I wondered in passing if the stuff about relptr_declare() was still needed to avoid confusing pgindent, since we tweaked the indent code a bit for macros that take a typename, but it seems that it still mangles "relptr(FooBar) some_struct_member;", putting extra whitespace in front of it. Hmmph.
