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.

2148 : : * by the calling loop in psql_completion(). Successful matches result in
2149 : : * calls to this function with the appropriate pattern_id, causing just the
2150 : : * corresponding switch case to be executed.
2151 : : *
2152 : : * If-conditions in this function can be more complex than a single *Matches
2153 : : * function call in one of two ways (but not both!). They can be OR's
2154 : : * of *Matches calls, such as
2155 : : * else if (Matches("ALTER", "VIEW", MatchAny, "ALTER", MatchAny) ||
2156 : : * Matches("ALTER", "VIEW", MatchAny, "ALTER", "COLUMN", MatchAny))

2164 : : * This is split out of psql_completion() primarily to separate code that

5891 : : * provided in completion_ref_schema. Those strings should be set up
5892 : : * by calling set_completion_reference or set_completion_reference_verbatim.

5898 : : * This is represented by a SchemaQuery object; see that typedef for details.

5900 : : * See top of file for examples of both kinds of query.
