Pending patches for logical replication will use this to determine
which columns of a tuple ought to be considered as its candidate key.

Since an increasing number of views and foreign tables are now able
to be updated, complete with any table, view, or foreign table in
the relevant contexts. This avoids the need to use a complex
query that may be both confusing to end-users and nonperformant
to construct the list of possible completions.

Add asprintf(), pg_asprintf(), and psprintf() to simplify string
allocation and composition. Replacement implementations taken from
NetBSD.

This allows reads to continue without any blocking while a REFRESH
runs. The new data appears atomically as part of transaction
commit.
Review questioned the Assert that a matview was not a system
relation. This will be addressed separately.

Merged after review with security patch f3ab5d4.
A materialized view has a rule just like a view and a heap and
other physical properties like a table. The rule is only used to
populate the table, references in queries refer to the
materialized data.
This is a minimal implementation, but should still be useful in
many cases. Currently data is only populated "on demand" by the
CREATE MATERIALIZED VIEW and REFRESH MATERIALIZED VIEW statements.
It is expected that future releases will add incremental updates
with various timings, and that a more refined concept of defining
what is "fresh" data will be developed. At some point it may even
be possible to have queries use a materialized in place of
references to underlying tables, but that requires the other
above-mentioned features to be working first.
Much of the documentation work by Robert Haas.

implement sepgsql still pending.
This adds the variable COMP_KEYWORD_CASE, which controls in what case
keywords are completed. This is partially to let users configure the
change from commit 69f4f1c3576abc535871c6cfa95539e32a36120f, but it
also offers more behaviors than were available before.
ANALYZE now accepts foreign tables and allows the table's FDW to control
how the sample rows are collected. (But only manual ANALYZEs will touch
foreign tables, for the moment, since among other things it's not very
clear how to handle remote permissions checks in an auto-analyze.)
contrib/file_fdw is extended to support this.

Over-optimization (by me, looks like :-() broke the case of recognizing
a word boundary just before a quoted identifier. Reported and diagnosed
by Dean Rasheed.
psql backslash commands that deal with file or directory names require
quotes around those that have spaces, single quotes, or backslashes.
However, tab-completing such names does not provide said quotes, and is
thus almost useless with them.
This patch fixes the problem by having a wrapper function around
rl_filename_completion_function that dequotes on input and quotes on
output. This eases dealing with such names.

This adds support for the more or less SQL-conforming USAGE privilege
on types and domains. The intent is to be able restrict which users
can create dependencies on types, which restricts the way in which
owners can alter types.

Make it return empty strings when there are no more words to the left of
the current position, instead of sometimes returning NULL and other times
returning copies of the leftmost word. Also, fetch the words in one scan,
rather than the previous wasteful approach of starting from scratch for
each word. Make the code a bit harder to break when someone decides we
need more words of context, too. (There was actually a memory leak here,
because whoever added prev6_wd neglected to free it.)
\ir is short for "include relative"; when used from a script, the

rather than to the current working directory.
