When a connection is closed, we also need to remove the hash entry
from the regular_list, as it now points to freed memory. To do this
store a reverse mapping from the connection to the hash string.
It would be nicer to introduce a wrapping structure for the pgsql
link resource that could store the hash (and notices), but that would
require large changes to the extension, so I'm going for a more
minimal fix here.
- New functions (each accepts a pgsql $connection resource):
. pg_connect_poll
. pg_socket
. pg_consume_input
. pg_flush
- Modified functions
The following functions now additionally return zero if the
underlying socket is set to non-blocking mode and the send
operation does not complete immediately. Previously these
functions returned only boolean TRUE/FALSE and blocked
execution while polling until all data was sent:
. pg_send_execute
. pg_send_prepare
. pg_send_query
. pg_send_query_params
- New constants
Used with pg_connect() to initiate an asynchronous connection
attempt:
. PGSQL_CONNECT_ASYNC
Used with pg_connection_status() to determine the current state
of an async connection attempt:
. PGSQL_CONNECTION_STARTED
. PGSQL_CONNECTION_MADE
. PGSQL_CONNECTION_AWAITING_RESPONSE
. PGSQL_CONNECTION_AUTH_OK
. PGSQL_CONNECTION_SSL_STARTUP
. PGSQL_CONNECTION_SETENV
Used with pg_connect_poll() to determine the result of an
async connection attempt:
. PGSQL_POLLING_FAILED
. PGSQL_POLLING_READING
. PGSQL_POLLING_WRITING
. PGSQL_POLLING_OK
. PGSQL_POLLING_ACTIVE
- Polling via returned pg_socket() stream
pg_socket() returns a read-only socket stream that may be
cast to a file descriptor for select (and similar) polling
operations. Blocking behavior of the pgsql connection socket
can be controlled by calling stream_set_blocking() on the
stream returned by pg_socket().
Use string escape for exotic types that allows to handle any data types. i.e. Array, JSON, JSONB, etc will work.
Add escape only query for better performance which removes meta data look up. Limitations forced by pg_convert() can be avoided with this. PGSQL_DML_ESCAPE constant is added for it.

(PHP pg_copy_from) Use non-deprecated API if it is available
(PHP pg_copy_to) Use non-deprecated API if it is available
