reduce the number of times TopoSort() has to be executed by trying to
extract multiple dependency loops from each pass, instead of only one.
This saves about another factor of ten on the regression database.
This could be considered as another exercise in grokking Fred Brooks'
maxim: Representation *is* the essence of programming.
one (use a priority heap to keep track of items ready to output, instead
of searching the input array each time). This brings the runtime of
pg_dump back to about what it was in 7.4.
pg_depend to determine a safe dump order. Defaults and check constraints
can be emitted either as part of a table or domain definition, or
separately if that's needed to break a dependency loop. Lots of old
half-baked code for controlling dump order removed.

definitions use pretty printing.
It does:
* Pretty index predicates
* Pretty rule definitions
* Uppercases PRIMARY KEY and UNIQUE to be consistent with CHECK and
FOREIGN KEY
* View rules are improved to match table rules:

proposal for eventually deprecating OIDs on user tables that I posted
earlier to pgsql-hackers. pg_dump now always specifies WITH OIDS or
WITHOUT OIDS when dumping a table. The documentation has been updated.

large objects. Dump all these in pg_dump; also add code to pg_dump
user-defined conversions. Make psql's large object code rely on
the backend for inserting/deleting LOB comments, instead of trying to
hack pg_description directly. Documentation and regression tests added.

data directory. Also fix handling of error conditions associated with
data directory checking step (can't use a boolean to distinguish four
possible result states...)
of option switches for backend, fix handling of COPY from data files so
that we won't have the newline-after-\. issue back again, add back some
comments and printouts lost from the shell script, etc. Still needs work
for error handling; in particular the shell version worked much more
nicely for the case of a postgres executable that fails on invocation.
offered for completion only when the input-so-far is at least 'pg_'.
This seems to be the best compromise behavior emerging from yesterday's
discussion. While at it, refactor code to eliminate repetitive use of
nearly identical queries, which was exceedingly tedious to maintain.
Also const-ify code more thoroughly in hopes of moving constant data into
text segment, and remove unnecessary length limit on queries.
"schema." has been typed. This allows readline to complete subsequent
characters immediately if all relations in the target schema start with
the same prefix. This actually worked before, but I unintentionally
broke it a few days ago.
Also, make completion schema-aware for GRANT, REVOKE, VACUUM.
