PHP & PostgreSQL
I'm switching from a MySQL environment to PGSQL and
I'm
going through and trying to learn the differences
between the
two. I've come across some issues that I can't seem
to find the
answers to in the docs or on the web. I'm hoping
someone can
help me out.
I'll try.

* MySQL has a function to reset the result set so
that it can be
iterated through again - mysql_data_seek(). I don't
see that there
is a similar function for PGSQL. Is that true? If
so, in order to
reset the result set you have to perform the query
again? Isn't
that a waste of resources?
In the PGSQL fetch functions, you usualy pass the row number
as a parameter. So you can iterate through the table as many times
as you want, just create a counter to control the iteration.

* For PGSQL, you can get the database name, the
field name
even the *host name* but you can't get the table name
from a
particular query?
I'm afraid that's true, at least I don't know such a function.
But I advise you to try the PEAR DB extension from PHP,
instead of using directly the database functions.
