You are in the wrong place, core doesn’t have this type.

I think it's basically a search path problem: the table's composite type
"vector" is masking the extension's type. Try schema-qualifying "vector"
with the appropriate schema name.

Right. Though my conclusion is this is why you don’t name a table something as generic as “vector”. But still one should schema-qualify their use of extension types anyway.

Thank you for your help!
I didn't know that the table name was actually a type. I specified a schema in front of the vector type, and the issue is resolved.
