Add "IWYU pragma: export" annotations in each catalog header file so that, for instance, including "catalog/pg_aggregate.h" is considered acceptable in place of "catalog/pg_aggregate_d.h". This is very common and it seems better to silence IWYU about it than trying to fix this up. Discussion: https://www.postgresql.org/message-id/flat/9395d484-eff4-47c2-b276-8e228526c8ae@eisentraut.org

|
|
* pg_amproc.h
|
|
* definition of the "access method procedure" system catalog (pg_amproc)
|
|
*
|
|
* The amproc table identifies support procedures associated with index
|
|
* operator families and classes. These procedures can't be listed in pg_amop
|
|
* since they are not the implementation of any indexable operator.
|
|
*
|
|
* The primary key for this table is <amprocfamily, amproclefttype,
|
|
* amprocrighttype, amprocnum>. The "default" support functions for a
|
|
* particular opclass within the family are those with amproclefttype =
|
|
* amprocrighttype = opclass's opcintype. These are the ones loaded into the
|
|
* relcache for an index and typically used for internal index operations.
|
|
* Other support functions are typically used to handle cross-type indexable
|
|
* operators with oprleft/oprright matching the entry's amproclefttype and
|
|
* amprocrighttype. The exact behavior depends on the index AM, however, and
|
|
* some don't pay attention to non-default functions at all.
