Attaching support for CREATE/ALTER/DROP EXTENSION ddl deparsing and replication.
One of the issues faced during replication of "CREATE EXTENSION.." was
that it internally
results in internally generated commands to create functions,
operators etc. If these
sql commands are replicated, then the actual "create extension"
command when replicated
will error out because of duplication. To avoid this, I used the
"in_extension" variable in the
"collected command" which is set when an extension is being created.
If this variable is set, then
avoid sql commands other than "CREATE EXTENSION" from being replicated.
This patch-set also adds a 5th patch from Vignesh C for supporting the
"GRANT" command.
However the following global objects are not supported:
1) Foreign data wrapper
2) parameter - ex: grant all on parameter wal_buffers TO test;
3) tablespace - ex: grant create on tablespace tbs1 to test;
4) database - ex: grant all on database postgres to test;
5) role - ex: grant test to test1; -- no event trigger for global objects
Thanks Vignesh!
