Postgres database schema visualizations.
Warning: This is very much a work in progress. It just does what I need it to do right now and makes some very strong assumptions about the databases (e.g. doesn't support passwordless auth and assumes that FOREIGN KEY is used properly throughout). Nevertheless, feel free to send PRs.
Install via
go get github.com/kdungs/go-pgviz
go install github.com/kdungs/go-pgviz
The program produces output in graphviz
format. You'll need to install that
in order to be able to render the output, e.g. via Homebrew on Mac OS using
brew install graphviz
. Then, you can simply use
go-pgviz | dot -Tpdf -o deps.pdf
By default, the program just displays the relationships between the tables. If
you want it to also list all columns, use the -show-columns
option. For more
information on command line parameters, use
go-pgviz -help
Usage of go-pgviz:
-db string
Postgres database
-host string
Postgres hostname (default "localhost")
-pass string
Postgres password
-port int
Postgres port (default 5432)
-show-columns
whether to show columns for each table
-show-relations
whether to show relationships between tables (based on foreign keys) (default true)
-user string
Postgres username (default "postgres")
