Creating a database dump for specific tables and entries Postgres
I have a database with hundreds of tables, what I need to do is export specified tables and insert statements for the data to one sql file.
The only statement I know can achieve this is
pg_dump -D -a开发者_如何学C -t zones_seq interway > /tmp/zones_seq.sql
Should I run this statement for each and every table or is there a way to run a similar statement to export all selected tables into one big sql big. The pg_dump above does not export the table schema only inserts, I need both
Any help will be appreciated.
Right from the manual: "Multiple tables can be selected by writing multiple -t switches"
So you need to list all of your tables
pg_dump --column-inserts -a -t zones_seq -t interway -t table_3 ... > /tmp/zones_seq.sql
Note that if you have several table with the same prefix (or suffix) you can also use wildcards to select them with the -t
parameter:
"Also, the table parameter is interpreted as a pattern according to the same rules used by psql's \d commands"
If those specific tables match a particular pattern, you can use that with the -t
option in pg_dump
.
pg_dump -D -a -t zones_seq -t interway -t "<pattern>" -f /tmp/zones_seq.sql <DBNAME>
For example to dump tables which start with "test", you can use
pg_dump -D -a -t zones_seq -t interway -t "^test*" -f /tmp/zones_seq.sql <DBNAME>
