In the pgoutput plugin, skip changes for relations that are not
publishable, per is_publishable_class(). This concerns in particular
materialized views and information_schema tables. While those relations
cannot be part of a publication, per existing checks, they will be
considered by a FOR ALL TABLES publication. A subscription would not
actually apply changes for those relations, again per existing checks,
but trying to match incoming changes to local tables on the subscriber
would lead to errors if no matching local table exists. Skipping those
changes on the publisher avoids sending useless changes and eliminates
the error.

A FOR ALL TABLES publication naturally considers all base tables to be a
candidate for replication. This includes transient heaps that are
created during a table rewrite during DDL. This causes failures on the
subscriber side because it will not have a table like pg_temp_16386 to
receive data (and if it did, it would be the wrong table).
The prevent this problem, we filter out any tables that match this
naming pattern and match an actual table from FOR ALL TABLES
publications. This is only a heuristic, meaning that user tables that
match that naming could accidentally be omitted. A more robust solution
might require an explicit marking of such tables in pg_class somehow.

Since we currently only have one protocol, this doesn't make much of a
difference other than the error message.

Don't move parenthesized lines to the left, even if that means they
flow past the right margin.
By default, BSD indent lines up statement continuation lines that are
within parentheses so that they start just to the right of the preceding
left parenthesis. However, traditionally, if that resulted in the
continuation line extending to the right of the desired right margin,
then indent would push it left just far enough to not overrun the margin,
if it could do so without making the continuation line start to the left of
the current statement indent. That makes for a weird mix of indentations
unless one has been completely rigid about never violating the 80-column
limit.
This behavior has been pretty universally panned by Postgres developers.
Hence, disable it with indent's new -lpl switch, so that parenthesized
lines are always lined up with the preceding left paren.
This patch is much less interesting than the first round of indent
changes, but also bulkier, so I thought it best to separate the effects.

Reformat various places in which pgindent will make a mess, and
fix a few small violations of coding style that I happened to notice
while perusing the diffs from a pgindent dry run.
There is one actual bug fix here: the need-to-enlarge-the-buffer code
path in icu_convert_case was obviously broken. Perhaps it's unreachable
in our usage? Or maybe this is just sadly undertested.
Lag tracking is called for each commit, but we introduce
a pacing delay to ensure we don't swamp the lag tracker.
