Copy or make a backup in postgresql database

After a long time without updating the blog, I return to do a little trick to managing a database in postgresql.

To copy the data and schema from a postgresql database we can use the following command:

 
 pg_dump-c mydbname> ARCHIVO.sql 
 

If you later want to enter this data into the database we can use this command: cat

 
 ARCHIVO.sql  then you re-use. Basically 
 

recursively parse all files. Rb. RBW and. Subdirectory c today seeking comment on the definition of each function and at the beginning of the file. With all this data creates HTML files in a subdirectory called "doc." An example of the result is: api.rubyonrails.com

To run you must call: rdoc

Some useful flags are:


- main [PATH to a file], the file will be targeted The startup appears as the generated documentation.
- all, includes private methods in the documentation (by default only includes the public).

- op [PATH to a directory], use this directory to save the documentation instead of "doc."

- inline-source, the source code of each method in the documentation.
