    "Could not access directory" PostgreSQL error in Windows

    After upgrading from PostgreSQL 9.2 to 9.3.4, I was no longer able to access my database from psql or pgAdmin:

    FATAL:  could not access directory
    "pg_tblspc/16639/PG_9.3_201306121/16843": Permission denied
    • This directory exists.
    • All user groups have full permissions to the directory as well as all its parent directories.

    PostgreSQL now requires a NETWORK SERVICE account, which it did not create. Since I was using PostgreSQL on the Home version of Windows 7 (64-bit), I cannot access the Local Group Policy Editor.

    One possibility is to transfer your database to a different OS.

    I solved it by restoring my database from production.
