9 /*----------------------------------------------------------------------
10 * This file implements a somewhat more sophisticated readline "TAB
11 * completion" in psql. It is not intended to be AI, to replace
12 * learning SQL, or to relieve you from thinking about what you're
13 * doing. Also it does not always give you all the syntactically legal
14 * completions, only those that are the most common or the ones that
15 * the programmer felt most like implementing.
17 * CAVEAT: Tab completion causes queries to be sent to the backend.
18 * The number of tuples returned gets limited, in most default
19 * installations to 1000, but if you still don't like this prospect,
20 * you can turn off tab completion in your ~/.inputrc (or else
21 * ${INPUTRC}) file so:
24 * set disable-completion on
27 * See `man 3 readline' or `info readline' for the full details.
30 * - Quotes, parentheses, and other funny characters are not handled
31 * all that gracefully.
