-- We define this schema in any pg source to support table event triggers.

-- There's a possibility of using metadata storage database as a source
|
|
-- (more likely if server is started with only --database-url option).
|
|
-- In this case, dropping the schema in this up (42 to 43) migration and re-creating the
|
|
-- same while defining as a pg source causes loss of event trigger logs.
|
|
-- To avoid this we won't drop the schema in this migration. While defining
|
|
-- a pg source we will define this schema only if this doesn't exist. This also
|
|
-- raises a question, "What happens if old database is only used as metadata storage?".
|
|
-- Then, definitely, this schema will be of no use. But, this helps a lot in down
|
|
-- migration (opposite to this migration, 43 to 42) as we create this schema only if this
|
|
-- doesn't exist.
