Specifies a role identify for use to develop the dump. this selection will cause pg_dump to problem a SET position rolename
When the concerned hosts have transformed, the connection info may need to get transformed. It may also be ideal to truncate the goal tables prior to initiating a whole new total desk duplicate. If people plan to duplicate First facts during refresh they need to make the slot with two_phase = Wrong. After the Original sync, the two_phase possibility will likely be automatically enabled from the subscriber When the subscription were at first created with two_phase = correct option.
the choice archive file formats needs to be utilized with pg_restore to rebuild the database. they permit pg_restore to get selective about what's restored, and even to reorder the objects prior to getting restored. The archive file formats are created to be portable throughout architectures.
With zstd compression, lengthy manner could Increase the compression ratio, at the price of amplified memory use.
Note that if you utilize this feature now, you probably also want the dump be in INSERT format, as เว็บตรง สล็อตฝากถอน ไม่มี ขั้นต่ํา 1 บาทก็ ถอนได้ being the COPY FROM through restore will not guidance row safety.
Dump info as INSERT instructions (instead of duplicate). This could make restoration pretty gradual; it is especially valuable for creating dumps that can be loaded into non-PostgreSQL databases. Any error all through restoring will induce only rows which might be Component of the problematic INSERT to be missing, instead of the whole table contents.
If no compression degree is specified, the default compression level might be applied. If just a degree is specified without mentioning an algorithm, gzip compression will likely be used if the extent is greater than 0, and no compression are going to be utilised if the extent is 0.
. The sample is interpreted according to the exact policies as for -t. --exclude-desk-information is often specified greater than at the time to exclude tables matching any of quite a few patterns. this feature is useful any time you need the definition of a specific table Regardless that you don't will need the data in it.
A directory format archive can be manipulated with regular Unix instruments; by way of example, documents within an uncompressed archive is usually compressed Together with the gzip, lz4, or zstd applications. This format is compressed by default working with gzip and also supports parallel dumps.
Therefore another access to the table won't be granted possibly and will queue following the unique lock request. This includes the worker system attempting to dump the table. with no safety measures This might be a vintage deadlock scenario. To detect this conflict, the pg_dump worker procedure requests One more shared lock utilizing the NOWAIT selection. If the worker method isn't granted this shared lock, somebody else need to have asked for an exclusive lock in the meantime and there's no way to carry on Using the dump, so pg_dump has no selection but to abort the dump.
, ...) VALUES ...). This will make restoration pretty slow; it is principally handy for creating dumps which might be loaded into non-PostgreSQL databases. Any mistake throughout restoring will trigger only rows that are A part of the problematic INSERT to be missing, in lieu of all the desk contents.
That is similar to the -t/--desk alternative, except that In addition it contains any partitions or inheritance kid tables from the table(s) matching the sample
It has to be supplied for your directory output structure on the other hand, where by it specifies the focus on Listing in lieu of a file. In cases like this the directory is developed by pg_dump and have to not exist before.
; this selects both the schema alone, and all its contained objects. When this selection is not specified, all non-technique schemas in the goal databases is going to be dumped. numerous schemas is often selected by creating several -n switches. The sample
for that customized and directory archive formats, this specifies compression of individual desk-data segments, along with the default is always to compress working with gzip at a reasonable stage. For plain text output, setting a nonzero compression degree brings about the whole output file being compressed, as if it had been fed as a result of gzip, lz4, or zstd; however the default is never to compress.
This option isn't vital, considering the fact that pg_dump will immediately prompt for a password In case the server demands password authentication.
