安装 Postgres 自定义类型 - 无法访问文件“...”：权限被拒绝

Question

Using postgres11, I'm trying to register the example Complex type that comes in the source distribution.

I've built the type without any problems:

git clone https://github.com/postgres/postgres.git
cd postgres/src/tutorial
make

But when I try to install it, I run into a permission problem:

~/p/s/tutorial> psql -U postgres -W 
Password: 
psql (11.2 (Debian 11.2-1.pgdg90+1))
Type "help" for help.

postgres=# \c testdata
Password for user postgres: 
You are now connected to database "testdata" as user "postgres".
testdata=# 
testdata=# \i complex.sql
psql:complex.sql:39: NOTICE:  type "complex" is not yet defined
DETAIL:  Creating a shell type definition.
psql:complex.sql:39: ERROR:  could not access file "/home/mnuttall/postgres/src/tutorial/complex": Permission denied
psql:complex.sql:47: ERROR:  type complex does not exist

I'm not sure where exactly the permission problem is coming from, as I've changed the permissions for everything in the src/tutorial directory to 777.

Anyone have an idea?

Answer 1

It looks like your home directory is not accessible to system user postgres .

You need to make sure that the permissions of the directories above allow user postgres to enter the directory ( rx ). So possible solution would be to run:

$ chmod o+rx $HOME

If this doesn't help make sure to run the command on every other directory in the path as well.
