Re: [GENERAL] Shared Objects (Dynamic loading)

Is there any way to check what all shared objects are loaded in the memory?
Also, when i say LOAD 'parser' where parser.so is the shared object i've
loaded dynamically
using CREATE FUNCTION, its says

ERROR: could not access file "parser": No such file or directory

Why would it give me this error?

Thanks and regards,
