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.

2156 : : * by the calling loop in psql_completion(). Successful matches result in
2157 : : * calls to this function with the appropriate pattern_id, causing just the
2158 : : * corresponding switch case to be executed.
2159 : : *
2160 : : * If-conditions in this function can be more complex than a single *Matches
2161 : : * function call in one of two ways (but not both!). They can be OR's
2162 : : * of *Matches calls, such as
2163 : : * else if (Matches("ALTER", "VIEW", MatchAny, "ALTER", MatchAny) ||
2164 : : * Matches("ALTER", "VIEW", MatchAny, "ALTER", "COLUMN", MatchAny))

5974 : : *
5975 : : * The query can be one of two kinds:

5977 : : * 1. A simple query, which must contain a restriction clause of the form
5978 : : * output LIKE '%s'

5980 : : * will be replaced by a LIKE pattern to match the already-typed text.

5982 : : * version of the string provided in completion_ref_object. If there is a
5983 : : * third '%s', it will be replaced by a suitably-escaped version of the string
5984 : : * provided in completion_ref_schema. Those strings should be set up
5985 : : * by calling set_completion_reference or set_completion_reference_verbatim.
5986 : : * Simple queries should return a single column of matches. If "verbatim"
5987 : : * is true, the matches are returned as-is; otherwise, they are taken to
5988 : : * be SQL identifiers and quoted if necessary.
5989 : : *
5990 : : * 2. A schema query used for completion of both schema and relation names.
5991 : : * This is represented by a SchemaQuery object; see that typedef for details.
5992 : : *
5993 : : * See top of file for examples of both kinds of query.
5994 : : *
5995 : : * In addition to the query itself, we accept a null-terminated array of
5996 : : * literal keywords, which will be returned if they match the input-so-far
5997 : : * (case insensitively). (These are in addition to keywords specified

6007 : : * readline will call this repeatedly with the same text and varying
6008 : : * state. On each call, we are supposed to return a malloc'd string
