Second pass at improving LIKE/regex estimation in non-C locales. It turns
out that it's actually quite likely that a string that is an extension of
the given prefix will sort as larger than the "greater" string our previous

against a modified string instead of just the bare prefix. We tack on

Improve the performance of LIKE/regex estimation in non-C locales, by making
make_greater_string() try harder to generate a string that's actually greater
than its input string. Before we just assumed that making a string that was
memcmp-greater was enough, but it is easy to generate examples where this is
not so when the locale is not C. Instead, loop until the relevant comparison
function agrees that the generated string is greater than the input.
Unfortunately this is probably not enough to guarantee that the generated
string is greater than all extensions of the input, so we cannot relax the
restriction to C locale for the LIKE/regex index optimization. But it should
at least improve the odds of getting a useful selectivity estimate in
prefix_selectivity(). Per example from Guillaume Smet.

Improve conversion of legacy CREATE CONSTRAINT TRIGGER representation of

we create a constraint; this will avoid creation of duplicate constraints
in scenarios where a broken FK constraint was repaired by re-adding the
constraint without removing the old partial trigger set. Basically, this will
work nicely in all cases where the FK was actually functioning correctly in
the database that was dumped. It will fail to restore an FK in just one case
where we theoretically could restore it: where we find the referenced table's
triggers and not the referencing table's trigger. However, in such a scenario
it's likely that the user doesn't even realize he still has an FK at all
(since the more-likely-to-fail cases aren't enforced), and we'd probably not
accomplish much except to cause the reload to fail because the data doesn't
meet the FK constraint. Also make the NOTICE logging still more verbose, by
adding detail about which of the triggers were found. This seems about all
we can do without solving the problem of getting the user's attention at

Remove the hack in the grammar that "optimized away" DEFAULT NULL clauses.
Instead put in a test to drop a NULL default at the last moment before
storing the catalog entry. This changes the behavior in a couple of ways:
* Specifying DEFAULT NULL when creating an inheritance child table will
successfully suppress inheritance of any default expression from the
parent's column, where formerly it failed to do so.
* Specifying DEFAULT NULL for a column of a domain type will correctly
override any default belonging to the domain; likewise for a sub-domain.
The latter change happens because by the time the clause is checked,
it won't be a simple null Const but a CoerceToDomain expression.

be consensus for that on pgsql-hackers, so refraining.

Ooops, fat-fingered last commit message. Should have
mentioned updating FAQ_IRIX for information about buggy MIPSPro
compiler version, now confirmed by Herve Boulouis.

Make pg_dump and friends consistently report both the filename and the
errno string when complaining of fopen failures. Per gripe from Bob
Pawley, it's not always instantly obvious to the user which name we
tried to open.

Fix a couple of issues with pg_dump's handling of inheritance child tables
that have default expressions different from their parent. First, if the
parent table's default expression has to be split out as a separate
ALTER TABLE command, we need a dependency constraint to ensure that the
child's command is given second. This is because the ALTER TABLE on the
parent will propagate to the child. (We can't prevent that by using ONLY on
the parent's command, since it's possible that other children exist that
should receive the inherited default.) Second, if the child has a NULL
default where the parent does not, we have to explicitly say DEFAULT NULL on
the child in order for this state to be preserved after reload. (The latter
actually doesn't work right because of a backend bug, but that is a separate
issue.)
Backpatch as far as 8.0. 7.x pg_dump has enough issues with altered tables
(due to lack of dependency analysis) that trying to fix this one doesn't seem
very productive.

Change text search parsing rules for hyphenated words so that digit strings
containing decimal points aren't considered part of a hyphenated word.
Sync the hyphenated-word lookahead states with the subsequent part-by-part
reparsing states so that we don't get different answers about how much text
is part of the hyphenated word. Per my gripe of a few days ago.
