[PATCH] Fix pg_isolation_regress to work outside its build directory - Mailing list pgsql-hackers

Hi,

isolation_main.c executes isolationtester with:

snprintf(psql_cmd + offset, sizeof(psql_cmd) - offset,
         SYSTEMQUOTE "\"./isolationtester\" \"dbname=%s\" < \"%s\" > \"%s\"

That obviously fails if pg_isolation_tester is invoked when CWD is not
its build directory. That's rather annoying if one wants to write an
isolation test for a contrib module or similar.
The attached patch fixes that using port.h's find_other_exec().

Greetings,

Andres Freund
