Comment (by strk):

 Having a literal `POSTGIS_REVISION` in the output of
 `postgis_full_version()` is unexpected, did you have trouble with SQLPP at
 build time ?
 How does postgis_config.h looks ? And `grep ^SQLPP postgis/Makefile`?

 In any case is

 currently] using

 TopMemoryContext] which is never automatically released by PostgreSQL
 backend so if any code path fails to explicitly release that memory you'd
 get such increasing memory usage until disconnect
