command line utility for importing XML, JSON, BYTEA document to PostgreSQL
This PostgreSQL command line utility (extension) is used for importing XML, any text or binary documents to PostgreSQL.
pgimportdoc -c 'insert into xmltab(x) values($1)' -t XML -f myxmldoc
for help run
pgimportdoc --help
XML documents are read in binary format - if XML doc has a header with encoding, then Postgres ensures encoding from XML encoding to PostgreSQL encoding.
Text documents are read in text format - there are translation from client encoding to PostgreSQL server encoding.
When format is BYTEA, then passing data are in bytea escaped text format.
Attention: The imported documents are completly loaded to client's memory. So you need enough free memory on client, when you would to use this tool. Maximal teoretical size of imported document is 1GB. More practical real maximal size is about 100MB.
ToDo:
- More input files support - options -f1 xxx -f2 xxx ... insert into .. values( $1, $2 )
- using LO API for passing binary data
- regress tests
Examples:
[pavel@localhost ]$ ./pgimportdoc postgres -f ~/Stažené/enprimeur.xml -c 'insert into xmldata values($1)' -t XML
[pavel@localhost ]$ cat ~/Stažené/enprimeur.xml | ./pgimportdoc postgres -c 'insert into xmldata values($1)' -t XML
[pavel@localhost ]$ cat ~/Stažené/enprimeur.xml | ./pgimportdoc postgres -E latin2 -c 'insert into doc values($1) returning id' -t TEXT
