Empty the pg_config system information view. This view keeps references to
|
||
|
|
several -dev outputs, which we want to avoid to keep closure size down.
|
||
|
|
|
||
|
|
The alternative to this patch would be to nuke references across the board,
|
||
|
|
but this will also affect the output of the pg_config utility. By emptying
|
||
|
|
the view only, we keep the pg_config binary intact. It resides in the -dev
|
||
|
|
output, so it's fine to have all those references there.
