Hi,
Here is my review. I agree with the goal of the refactoring, as we want
to make it easier to dump all the properties for the database object.
But I think we need to solve the issues with the special casing of
postgres and template1 which I personally would find very surprising if
pg_dump -C did. On the other hand I think that we cannot get away from
having pg_dumpall give them a special treatment.
The nitpicking section is for minor code style errors.
= Functional review
I have not done an in depth functional review due to the discussion
about how postgres and template1 should be handled.
- The patch does not apply cleanly anymore
- I do not like the change in behavior which causes "pg_dump -C
postgres" to no longer include CREATE DATABASE. Special treatment of
specific databases based on name makes sense in pg_dumpall, but not in
pg_dump.
- There are test failures in the pg_dump tests. It seems like some could
be related to that you do not include CREATE DATABASE postgres in the
dumps but I also get errors like 'ERROR: syntax error at or near
"fault_tablespace"'.
not ok 691 - createdb: dumps CREATE DATABASE postgres
not ok 3003 - pg_dumpall_dbprivs: dumps CREATE DATABASE dump_test
not ok 11 - restore full dump using environment variables for connection
parameters
not ok 12 - no dump errors
not ok 13 - restore full dump with command-line options for connection
parameters
not ok 14 - no dump errors
= Code review
- As a response to "TBD -- is it necessary to get the default encoding":
I think so, but either way changing this seems unrelated to this patch.
- I know it is taken from the old pg_dumpall code, but the way the
database owner is handled seems I wrong.think we should set it like the
owner for other objects. And more importantly it should respect --no-owner.
- The logic for switching database when setting the default table space
is broken. You generate "\ connect" rather than "\connect".
- I saw the comment "Note that we do not support initial privileges
(pg_init_privs) on databases." and wondered: why not? I definitly think
that we should support this.
= Nitpicking
- You should probably use SGML style </> over </command> and
</application> for inline tags.
- In "database-level properties such as Ownership, ACLs, [...]" I do not
think that "Ownerships" shuld be capitalized.
- There are two extra spaces on the lines below, and a space is missing
after the closing tag.
<command> ALTER ROLE IN DATABASE ... SET </command>commands.
with --create option to dump <command> ALTER ROLE IN DATABASE ... SET
</command>
- On the following comment ".." should be "...", since that is the
correct way to write an ellipsis.
* Frame the ALTER .. SET .. commands and fill it in buf.
- Rename arrayitem to configitem in makeAlterConfigCommand().
- In makeAlterConfigCommand() you should do "*pos++ = '\0';" rather than
"*pos = 0;" and then remove the later + 1 so our code matches with the
code in dumpFunc(). Either is correct, but it would be nice if both
pieces of code looked more similar.
- You removed an empty line in pg_backup_utils.h between globals
variables and function declartions which I think should be left there.
It should be directly after g_verbose.
- There is something wrong with the indentation of the query for
collecting info about databases in dumpDatabase() for PG >= 9.6.
- Missing space before "'' as rdatacl" in dumpDatabase(), and a missing
space at the end of the string.
- Double space in 'FROM pg_database "' in dumpDatabase().
