17 : * This file implements a somewhat more sophisticated readline "TAB
18 : * completion" in psql. It is not intended to be AI, to replace
19 : * learning SQL, or to relieve you from thinking about what you're
20 : * doing. Also it does not always give you all the syntactically legal
21 : * completions, only those that are the most common or the ones that
22 : * the programmer felt most like implementing.
23 : *
24 : * CAVEAT: Tab completion causes queries to be sent to the backend.
25 : * The number of tuples returned gets limited, in most default
26 : * installations to 1000, but if you still don't like this prospect,
27 : * you can turn off tab completion in your ~/.inputrc (or else
28 : * ${INPUTRC}) file so:
29 : *
30 : * $if psql
31 : * set disable-completion on
32 : * $endif
33 : *
34 : * See `man 3 readline' or `info readline' for the full details.
35 : *
36 : * BUGS:
37 : * - Quotes, parentheses, and other funny characters are not handled
38 : * all that gracefully.

2087 : * with many-arm switches than many-arm else-if chains.
2088 : *
2089 : * Each if-condition in this function must begin with a call of one of the
2090 : * functions Matches, HeadMatches, TailMatches, MatchesCS, HeadMatchesCS, or
2091 : * TailMatchesCS. The preprocessor gen_tabcomplete.pl strips out those
2092 : * calls and converts them into entries in tcpatterns[], which are evaluated
2093 : * by the calling loop in psql_completion(). Successful matches result in
2094 : * calls to this function with the appropriate pattern_id, causing just the
2095 : * corresponding switch case to be executed.
2096 : *
2097 : * If-conditions in this function can be more complex than a single *Matches
2098 : * function call in one of two ways (but not both!). They can be OR's
2099 : * of *Matches calls, such as
2100 : * else if (Matches("ALTER", "VIEW", MatchAny, "ALTER", MatchAny) ||
2101 : * Matches("ALTER", "VIEW", MatchAny, "ALTER", "COLUMN", MatchAny))
2102 : * or they can be a *Matches call AND'ed with some other condition, e.g.

2104 : * !ends_with(prev_wd, ','))
2105 : * The former case is transformed into multiple tcpatterns[] entries and

2108 : *
2109 : * This is split out of psql_completion() primarily to separate code that
