Handle extension members when first setting object dump flags in pg_dump.
pg_dump's original approach to handling extension member objects was to run around and clear (or set) their dump flags rather late in its data collection process. Unfortunately, quite a lot of code expects those flags to be valid before that; which was an entirely reasonable expectation before we added extensions. In particular, this explains Karsten Hilbert's recent report of pg_upgrade failing on a database in which an extension has been installed into the pg_catalog schema. Its objects are initially marked as not-to-be-dumped on the strength of their schema, and later we change them to must-dump because we're doing a binary upgrade of their extension; but we've already skipped essential tasks like making associated DO_SHELL_TYPE objects. To fix, collect extension membership data first, and incorporate it in the initial setting of the dump flags, so that those are once again correct from the get-go. This has the undesirable side effect of slightly lengthening the time taken before pg_dump acquires table locks, but testing suggests that the increase in that window is not very much. Along the way, get rid of ugly special-case logic for deciding whether to dump procedural languages, FDWs, and foreign servers; dump decisions for those are now correct up-front, too. In 9.3 and up, this also fixes erroneous logic about when to dump event triggers (basically, they were *always* dumped before). In 9.5 and up, transform objects had that problem too. Since this problem came in with extensions, back-patch to all supported versions.

* getExtensionMembership --- obtain extension membership data
|
||||
*
|
||||
* There are three main parts to this process:
|
||||
*
|
||||
* 1. Identify objects which are members of extensions
|
||||
*
|
||||
* Generally speaking, this is to mark them as *not* being dumped, as most
|
||||
* extension objects are created by the single CREATE EXTENSION command.
|
||||
* The one exception is binary upgrades with pg_upgrade will still dump the
|
||||
* non-table objects.
|
||||
*
|
||||
* 2. Identify and create dump records for extension configuration tables.
|
||||
*
|
||||
* Extensions can mark tables as "configuration", which means that the user
|
||||
* is able and expected to modify those tables after the extension has been
|
||||
* loaded. For these tables, we dump out only the data- the structure is
|
||||
* expected to be handled at CREATE EXTENSION time, including any indexes or
|
||||
* foreign keys, which brings us to-
|
||||
*
|
||||
* 3. Record FK dependencies between configuration tables.
|
||||
*
|
||||
* Due to the FKs being created at CREATE EXTENSION time and therefore before
|
||||
* the data is loaded, we have to work out what the best order for reloading
|
||||
* the data is, to avoid FK violations when the tables are restored. This is
|
||||
* not perfect- we can't handle circular dependencies and if any exist they
|
||||
* will cause an invalid dump to be produced (though at least all of the data
|
||||
* is included for a user to manually restore). This is currently documented
|
||||
* but perhaps we can provide a better solution in the future.
|
||||
* We need to identify objects that are extension members as soon as they're
|
||||
* loaded, so that we can correctly determine whether they need to be dumped.
|
||||
* Generally speaking, extension member objects will get marked as *not* to
|
||||
* be dumped, as they will be recreated by the single CREATE EXTENSION
|
||||
* command. However, in binary upgrade mode we still need to dump the members
|
||||
* individually.

* 1. Identify and create dump records for extension configuration tables.
|

*
|

* Extensions can mark tables as "configuration", which means that the user

* is able and expected to modify those tables after the extension has been
|

* loaded. For these tables, we dump out only the data- the structure is
|
||||
* expected to be handled at CREATE EXTENSION time, including any indexes or
|
||||
* foreign keys, which brings us to-
|
||||
*
|
||||
* 2. Record FK dependencies between configuration tables.
|
||||
*
|
||||
* Due to the FKs being created at CREATE EXTENSION time and therefore before
|
||||
* the data is loaded, we have to work out what the best order for reloading
|
||||
* the data is, to avoid FK violations when the tables are restored. This is
|
||||
* not perfect- we can't handle circular dependencies and if any exist they
|
||||
* will cause an invalid dump to be produced (though at least all of the data
|
||||
* is included for a user to manually restore). This is currently documented
|
||||
* but perhaps we can provide a better solution in the future.
