Is there something that provides auto-completion for PostgreSQL? I'm looking for something similar to RedGate's SQLPrompt. Currently using pgAdmin III's query tool but willing to consider other query editors.
To use autocomplete, begin typing your query; when you would like the Query editor to suggest object names or commands that might be next in your query, press the Control+Space key combination.
I recently discovered in PGAdmin III that you can autocomplete/activate intellisense by hitting Ctrl+Space.
Special character symbols are characters with a pre-defined syntactic meaning in PostgreSQL. They are typically disallowed from being used in identifier names for this reason, though as mentioned in the section on quoted identifiers, this restriction can usually be worked around with quotes if need be.
Use \l or \l+ in psql to show all databases in the current PostgreSQL server. Use the SELECT statement to query data from the pg_database to get all databases.
Use source option to load autocomplete data using jQuery AJAX. Send AJAX POST request to ajaxfile.php, set dataType to json, and pass typed values as data. On successful callback pass data to response (). Using select event to display selected option label in the #autocomplete and value in #selectuser_id input fields.
We will be using Python, Postgres and Spacy. Elastic Search is a very good alternative to Postgres, but for simple tasks not involving millions and millions of rows, Postgres, despite having no in-memory capabilities, is not too shabby. Here is an interesting article highlighting the differences between the two.
GiST (Generalized Search Tree) and GIN (Generalized Inverted Index) are two kinds of indices in Postgres. Adding an index is not mandatory, but desirable to speed up queries. At this point, I really can’t recommend GiST or GIN since I’ve had varying performance differences between them in the past.
psql has it. I'm using version 8.2.7 on server version 8.2.6
