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.
16 : *
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:
22 : *
23 : * $if psql
24 : * set disable-completion on
25 : * $endif
26 : *
27 : * See `man 3 readline' or `info readline' for the full details.
28 : *
29 : * BUGS:
30 : * - Quotes, parentheses, and other funny characters are not handled
31 : * all that gracefully.
