Re: Testing autovacuum wraparound (including failsafe)

[Peter Eisentraut]

The way src/test/modules/xid_wraparound/meson.build is written, it 
installs the xid_wraparound.so module into production installations. 
For test modules, a different installation code needs to be used.  See 
neighboring test modules such as 
src/test/modules/test_rbtree/meson.build for examples.
