Changed PDO::lastInsertId() to have following proto:

string PDO::lastInsertId([string name])

this allows arbitrary unique identitifers to be returned from the driver.

The optional name parameter is for databases that require additional contextual
information to be able to return the correct identifier. None currently use
it, but pgsql will be on the list of drivers that do.

Decode pgsql LOB objects (bytea type) on fetch

Use the created connection string.

Add support for fetching meta data

Eliminate unused parameter.
Don't start a transaction when asking for a cursor with pgsql.
Fix parameter binding for sqlite3

Allow drivers to select bind emulation on a per statement basis

Use PQescapeBytea() for quoting. Need to think how to add binary safe
quoting for blobls (pgsql bytea type).
Fixes #2818

Take a blind stab at implementing scrollable cursors for pgsql.
We allocate a unique cursor name for each statement, so that we
don't interfere with other open statement handles on the same dbh.

Note, however, that we force a new transaction for each open scrollable cursor
(postgres requires cursors to be used inside a transaction). This is okay,
except for the case where a scrollable cursor is opened, an update is made and
the cursor is closed; closing the cursor commits the transaction that was begun
when it was opened.

It might well be better to avoid the transaction in PDO and force the user to
be aware of the requirements of cursors and explicitly initiate the transaction
themselves.

This is all untested code; it compiles and looks like it will work, but I
encourage someone with a real postgres setup to actually sit down and try to
use it.

lame implementation of SQLSTATE error codes

Make handle error messages handle persistent situations better.

more method table adjustments.
mysql driver needs work with the error message stuff.
Other drivers need a bit more auditing...

Proper parameter separators for PostgreSQL connection initialization.

- Trim error messages

- Fix shutdown problems

equivalent segv/shutdown fix for failed connect

Allow pgsql driver to accept login & password as separate parameters like
other PDO drivers can.

PQfreemem() is only available in 7.4

Whitespace: editor in the wrong mode ;)
