I ran into this warning when we switched from one version of Postgres to
another.
It complains when the view is created, but it works fine when I select from
it.
But I don't mix E' and \\
My views have strings like '\\.[0-9]+\\.'
Your view has both E' and \\ -- could it be that if you have E' you only
need \, not \\
