RE: Regression test fails when 1) old PG is installed and 2) meson/ninja build is used

Dear Andrew,

To confirm, did you ask the LD_LIBRARY_PATH on my bash? Here it is:

```bash
$ echo $LD_LIBRARY_PATH 
/usr/local/pgsql/lib:/usr/local/lib:/usr/lib64/
```

I modified the first one to refer lib64 dir, but the result is not changed.
