Subject: Teach asset.merge_record_assets about STRING_AGG()
X-Git-Url: https://old-git.evergreen-ils.org/?a=commitdiff_plain;h=001d6b909cd9f6f21e2fb6bc21a54d9ee247f69a;p=working%2FEvergreen.git

Teach asset.merge_record_assets about STRING_AGG()

Now that asset.merge_record_assets() is working, cut over to
STRING_AGG() so it can iterate over those unnecessary nodes faster :)
