Hello.
I have database with installed pg_trgm extension with module path
'/usr/lib/pg_trgm' (yes, this is mistake without $libdir (: ). Now I
want upgrade postgresql to new major version. I keep old version 9.3 in
/opt/postgresql/9.3 and new version 9.6 in /usr. Old version $libdir -
/opt/postgresql/9.3/lib, new version $libdir - /usr/lib/postgresql. So
now I am in trap because old version try to load shared libarry from
'/usr/lib/pg_trgm'. So I want change '/usr/lib/pg_trgm' to
'$libdir/pg_trgm' for old database. And I have only one ugly solution:
replace '/usr/lib/pg_trgm' with '$libdir//pg_trgm' in table files
(/usr/lib - 8 chars, $libdir/ - 8 chars).
May be someone has better solution?
Thanks.
