search_path set and seen but not used!
Double quotes denote identifiers that contain special characters, so set search_path to "blip_schema,public" will set the search path to a single schema named blip_schema,public. 

The names you supply to set search_path have to follow regular naming rules, so no quotes at all, unless you have one schema that requires quoting:

set search_path to blip_schema,public;


or if you do want to use quotes, you need them for each identifier:

set search_path to "blip_schema","public";
