command line utility for importing XML, JSON, BYTEA document to PostgreSQL

This PostgreSQL command line utility (extension) is used for importing XML, any text orbinary 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 Postgresensures encoding from XML encoding to PostgreSQL encoding.

Text documents are read in text format - there are translation from client encoding toPostgreSQL 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 freememory on client, when you would to use this tool. Maximal teoretical size of imported documentis 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
