Outdated gin/gist links to Postgres documentation

[Russ Ferriday]

In the paragraph in the latest (and earlier) docs:

​https://docs.djangoproject.com/en/dev/ref/contrib/postgres/indexes/#django.contrib.postgres.indexes.GinIndex

the built-in operator classes reference points at

​https://www.postgresql.org/docs/current/gin-builtin-opclasses.html

But the Postgres docs have been reorganised and this link gives "Page not found"

I suggest the following new url, but please check me.

​https://www.postgresql.org/docs/17/gin.html#GIN-BUILTIN-OPCLASSES

Whether you replace 17 with current depends on how much you think the structure of the PG docs will change.

There are likely to be similar dangling references around this area

Well spotted thank you!

These are ones I found, there could be more:

• ​https://www.postgresql.org/docs/current/gin-builtin-opclasses.html -> ​https://www.postgresql.org/docs/current/gin.html#GIN-BUILTIN-OPCLASSES
• ​https://www.postgresql.org/docs/current/gin-implementation.html#GIN-FAST-UPDATE -> ​https://www.postgresql.org/docs/current/gin.html#GIN-FAST-UPDATE
• ​https://www.postgresql.org/docs/current/gist-builtin-opclasses.html -> ​https://www.postgresql.org/docs/current/gist.html#GIST-BUILTIN-OPCLASSES
• ​https://www.postgresql.org/docs/current/gist-implementation.html#GIST-BUFFERING-BUILD -> ​https://www.postgresql.org/docs/current/gist.html#GIST-BUFFERING-BUILD
