Specifies the TCP port or local Unix area socket file extension on which the server is listening for connections. Defaults to the PGPORT surroundings variable, if set, or possibly a compiled-in default.
If your involved hosts have transformed, the connection facts may need to be modified. It might also be suitable to truncate the goal tables prior to initiating a whole new full table copy. If users plan to copy First info through refresh they need to make the slot with two_phase = Phony. following the Preliminary sync, the two_phase possibility might be mechanically enabled via the subscriber In case the membership were at first designed with two_phase = correct solution.
this feature will make no variance if there aren't any browse-produce transactions Lively when pg_dump is commenced. If read-publish transactions are active, the start of the dump could be delayed for an indeterminate length of time. as soon as jogging, efficiency with or without the change is the same.
parameter is interpreted to be a sample in accordance with the similar policies employed by psql's \d commands (see designs), so multiple extensions can even be selected by composing wildcard people in the sample.

Output SQL-common SET SESSION AUTHORIZATION instructions instead of ALTER proprietor commands to find out item possession. This makes the dump a lot more benchmarks-appropriate, but with regards to the background in the objects during the dump, may not restore properly.
When employing wildcards, be mindful to estimate the pattern if desired to avoid the shell from expanding the wildcards; see illustrations under. the sole exception is the fact an vacant pattern is disallowed.
Output instructions to DROP all of the dumped database objects prior to outputting the commands for building them. This option is helpful once the restore should be to overwrite an existing databases.
A Listing structure archive is usually manipulated with regular Unix resources; such as, information in an uncompressed archive may be compressed with the gzip, lz4, or zstd resources. This format is compressed by default utilizing gzip and also supports parallel dumps.
power quoting of all identifiers. this feature is suggested when dumping a database from the server whose PostgreSQL main Model differs from pg_dump's, or if the output is intended to get loaded into a server of a special big Edition.
, ...) VALUES ...). This will make restoration quite gradual; it is principally valuable for generating dumps that can be loaded into non-PostgreSQL databases. Any mistake for the duration of restoring will trigger only rows which are Component of the problematic INSERT to get misplaced, instead of your complete table contents.
. The timeout could be laid out in any in the formats recognized by SET statement_timeout. (Allowed formats change dependant upon the server version you are dumping from, but an integer range of milliseconds is acknowledged by all variations.)
It has to be provided for the Listing output structure nevertheless, where it specifies the focus on Listing rather than a file. In this instance the directory is established by pg_dump and should not exist just before.

Use a serializable transaction with the dump, to make certain that the snapshot made use of is consistent with afterwards database states; but do that by awaiting a point within the transaction stream at which no anomalies might be present, making sure that There's not a risk on the dump failing or creating other transactions to roll back again that สล็อตทดลอง has a serialization_failure. See Chapter 13 For more info about transaction isolation and concurrency Handle.
