GUI administration tool for Postgres
Postgres has a binary windows installer package, which includes pgAdmin
There is a system path warning for conflicts with Cygwin; if Cygwin is installed, some dll's won't mix well
Installed as a service on Win32, creating a user'postgres' with a randomly generated password
port 5432, checked box to accept connections from all hosts
pgAdmin has a tips file at 'pgadmin III/docs/en_US/tips.txt'
database encoding warning - default database encoding is SQL_
ASCII, but many files are UTF8 or other ecoding; make sure to specify an encoding with the createdb commands below
restoring a database from a sql script file (such as example databases and database dumps):
createdb dbname (enter) (then enter your password)
psql -f db_sql_file.sql [-d] dbname (enter) (enter your password)
you may also want to set the encoding: createdb –encoding UTF8 dbname

list available databases:
backticks (`) don't work in Postgres (commonly used in MySQL)
common primary key type in MySQL: “int(11) NOT NULL auto_increment” in Postgres is “serial”, and a sequence is automatically created for the increment
type blob is bytea in Postgres
in expressions, _ (underscore) matches any single character, and % (percent) matches any string of zero or more characters
escapes and string constants are covered in section 4.1.2.1 of the Postgres documentation; to escape a single quote, precede it with another: ''
by default, for security reasons, Postgres does not listen on all available IP addresses; this needs enabled in data/postgresql.conf:
to access the db from another host, you must edit data/pg_hba.conf
to add a local subnet, use something like: host all all 192.168.0.0/24 md5
be careful with any lines ending with 'trust', because those hosts will be allowed access unconditionally, without asking for a password
to reload PostgreSQL, such as for configuration file changes, you can use:
pg_ctl reload [-D DATADIR] [-s]
