Hello All, I am trying to install PostgreSQL 16.4 on AIX 7.1. I get an error at initdb step : performing post-bootstrap initialization ... 2024-09-12 12:09:07.075 CEST [14745748] FATAL: permission denied for table pg_description This version of PostgreSQL was build on this machine with IBM XL C compiler 10.1 : export OBJECT_MODE=64 $srcdir/configure --prefix=$instdir --without-icu make make install When I run initdb with -n option, I can see that files in PGDATA directory seem to have expected permissions. I have tried to install PostgreSQL 15.1, 16.0 and 16.3 but got the same error with all these versions. Any help would be appreciated. François
