Variable-length catalog columns have been declared like
text attoptions[1];
but that "1" has always been a fiction. Before the use of #ifdef
CATALOG_VARLEN, these declarations were visible to the C compiler, and
this was also before flexible array members were universally available,
so this was just a convenient workaround to make this compile. But
these reasons are long gone, and the "1" is now just a confusing relic.
Change this to
text attoptions[];
which more intuitively reflects the actual nature of these fields (while
still being syntactically valid but semantically invalid C code).
Catalog.pm could already parse both spellings, but no existing code used
bare []. To enforce future consistency, it is changed to no longer
permit digits between the brackets.
(Obviously, catalog definitions are not backpatched, so this shouldn't
create any new maintenance burden.)

Subject: [PATCH] Declare variable-length catalog columns as [] rather than [1]
Variable-length catalog columns have been declared like
text attoptions[1];
but that "1" has always been a fiction. Before the use of #ifdef
CATALOG_VARLEN, these declarations were visible to the C compiler, and
this was also before flexible array members were universally
available, so this was just a convenient workaround to make this
compile. But these reasons are long gone, and the "1" is now just a
confusing relic. Change this to
text attoptions[];
which more intuitively reflects the actual nature of these
fields (while still being syntactically valid but semantically invalid
C code).
Catalog.pm could already parse both spellings, but no existing code
used bare []. To enforce future consistency, it is changed to no
longer permit digits between the brackets.
