That's the problem: not really practical in a wider ecosystem of C libraries, especially if the library produces multiple versions. (Or, not practical unless someone writes some credible symbol-version-mangling-magic) But is it unsurmountable? -- dlsym returns a function pointer, and one would build up the operator table for the version of the extension at hand, so one might have ltree "version 1.01" and ltree "version 2.3" fields in the same database. -- fdr -- Sent via pgsql-hackers mailing list (pgsql-hackers@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-hackers
