Cannot link against libpq on macOS

2023-09-20 Thread A. Reichstadt
Hello,

I have been struggling with trying to use a current version of libpq to link 
against on macOS in Xcode. It seems that nothing works, nobody on the web 
eventually succeeded either as far as I found so far. I try to write a small 
sample client. I started with the public source download to built libpq itself, 
which did work. But I am lost as to what files to actually include in my 
project then. I dragged lib, include, libpq into my project, but then it the 
compiler complains about the header internal references, so I need to remove 
lib/ in front of any includes in files, or it doesn’t get found. It makes no 
difference if I add Linker flags or search paths.

PLease, can someone help?

Thanks,
Alex



How to deny access to Postgres when connected from host/non-local

2021-04-03 Thread A. Reichstadt
Hello,

I try to deny access to all databases on my server if the user “postgres" tries 
to connect from a non-local host. Here is what I did in pg_hba.conf:


# TYPE  DATABASEUSERADDRESS METHOD

# "local" is for Unix domain socket connections only
local   all all md5
# IPv4 local connections:
hostall all 127.0.0.1/32md5
# IPv6 local connections:
hostall all ::1/128 md5
# Allow replication connections from localhost, by a user with the
# replication privilege.
local   replication all md5
hostreplication all 127.0.0.1/32md5
hostreplication all ::1/128 md5
hostall all 0.0.0.0/0   md5
local   all postgrestrust
hostall postgres0.0.0.0/0   reject


But it continues to allow for Postgres to connect from anywhere through PGAdmin 
but also as a direct connection to port 5432. I also relaunched the server. 
This is version 12.

What else do I have to do?

Thanks for any help.

Cheers,
Alex
