Subject: Adjust things for the is_literal_value and -ident SQLA 1.80 fixes
X-Git-Tag: v0.082801~3
X-Git-Url: http://git.shadowcat.co.uk/gitweb/gitweb.cgi?a=commitdiff_plain;h=f6fff270;p=dbsrgits%2FDBIx-Class.git

Adjust things for the is_literal_value and -ident SQLA 1.80 fixes

(SQLA commits 52ce7dca and ddd6fbb6f)

The Oracle workaround is absolutely horrific and needs to be redone from
scratch. For the time being the tests seem to pass, so punt for later... sigh
