item, if the page containing the current item is split while the indexscan
is stopped and holds no read-lock on the page. The current item might
move right onto a page that the indexscan holds no pin on. In the prior
code this would allow btbulkdelete to reach and possibly delete the item,
causing 'my bits moved right off the end of the world!' when the indexscan
finally resumes. Fix by chaining read-locks to the right during
_bt_restscan and requiring btbulkdelete to LockBufferForCleanup on every
page it scans, not only those with deletable items. Per my pghackers
message of 25-May-02. (Too bad no one could think of a better way.)

whose conditions might yield NULL. The negated qual to attach to the
original query is properly 'x IS NOT TRUE', not 'NOT x'. This fix
produces correct behavior, but we may be taking a performance hit because
the planner is much stupider about IS NOT TRUE than it is about NOT
clauses. Future TODO: teach prepqual, other parts of planner how to
cope with BooleanTest clauses more effectively.

SPI_prepare: they all save the prepared plan into topCxt, and so the
procCxt copy that's actually returned by SPI_prepare ought to be freed.

caused other problems. Will need to wait for the backend to properly fix
the root problem.

rather than being reordered according to INSTEAD attribute for
implementation convenience.
Also, increase compiled-in recursion depth limit from 10 to 100 rewrite
cycles. 10 seems pretty marginal for situations where multiple rules
exist for the same query. There was a complaint about this recently,
so I'm going to bump it up. (Perhaps we should make the limit a GUC
parameter, but that's too close to being a new feature to do in beta.)

Ray Ontko 28-June-02. Also, fix prefix_selectivity for NAME lefthand
variables (it was bogusly assuming binary compatibility), and adjust
make_greater_string() to not call pg_mbcliplen() with invalid multibyte
data (this last per bug report that I can't find at the moment, but it
was in July '02).

All right, this is it. This patch merely checks if child tables have
the column. If atttypid and atttypmod are the same, the attributes'
attinhcount is incremented; else the operation is aborted. If child
tables don't have the column, recursively add it.
attislocal is not touched in any case.

specifically ceil(), floor(), and sign(). There may be other functions
that need to be added, but this is a start. I've included some simple
regression tests.

a column list. Bring its parsing of quoted names and quoted strings
somewhat up to speed --- I believe it now handles all non-error cases
the same way the backend would, but weird boundary conditions are not
necessarily done the same way.

the mistake in future.
