PostgreSQL is an advanced object-relational database management system that supports extended SQL standard subsets.
When PostgreSQL versions earlier than 9.3.3, 9.2.7, 9.1.12, 9.0.16, and 8.4.20 run the "make check" regression test in the constructor tree, the server process allows users on the same mac

Note: If you do not want to use the. pgpass file, you can add the-W option in the command line, which means entering the password and then executing it.
Appendix: basic operations suitable for O M of PostgreSQL databases
Log on to the PostgreSQL database:
Psql-U dbuser-d exampledb-h 127.0.0.1-p 5432
If you do not want to enter the password, run the following command:
Psql "host = 127.0.0.1 hostaddr = 127.0.0.1
Php updates the solution for database interruption. You can solve this problem: set_time_limit (900); this function specifies the maximum execution time of the current php script. although the set value is 900 seconds, the actual maximum execution time is = php. max_ex in ini:
Set_time_limit (900 );
This function specifies the maximum execution time of the current php script,
Although the value is set to 900 seconds
Maximum execution time = max_execution_time value in php. ini-time when the

The above operations basically complete the installation of the entire PostgreSQL.
