travis failing regress

[robe]

Travis has been failing regress since my #899 commits, but the errors don't seem to be breaking any where there so might be something unrelated.

I'm fixing run_test to honour -v in this case, so we get the actual error message

Here it is: 00-regress-install/lib/postgis-2.2.so: undefined symbol: HeapTupleHeaderGetDatum

From ​https://travis-ci.org/postgis/postgis/builds/31147383#L1944

Thats with PostgreSQL 9.1.4: ​https://travis-ci.org/postgis/postgis/builds/31147383#L962

Do Debbie or Winnie build against 9.1.4 ?

[strk]

The compiler invocation has an explicit -I/usr/include, which comes before -I/usr/include/postgresql/9.1/server, so I'm thinking there might be a conflict between the postgresql header used and the library linked against.

debbie builds against PostgreSQL 9.1.9 winnie builds too against PostgreSQL 9.1.9 on x86_64-w64-mingw32 (testing in mingw mode instead of edb mode)

On last run both 9.1s passed.

Was a problem about having mixed postgres installs, fixed as of r12845: ​https://travis-ci.org/postgis/postgis/builds/31227108
